Cadmium telluride (CdTe) is a crystalline compound formed from cadmium and tellurium. It is used as an infrared optical window and a solar cell material. It is usually sandwiched with cadmium sulfide to form a p-n junction photovoltaic solar cell. Typically, CdTe cells use a n-i-p structure.


CdTe is a highly useful material in the making of thin film solar cells. Thin-film CdTe provides a cost-effective solar cell design, but is less efficient than polysilicon.
CdTe can be alloyed with mercury to make a versatile infrared detector material (HgCdTe). CdTe alloyed with a small amount of zinc makes an excellent solid-state X-ray and gamma ray detector (CdZnTe).
CdTe is used as an infrared optical material for optical windows and lenses but it has small application and is limited by its toxicity such that few optical houses will consider working with it. An early form of CdTe for IR use was marketed under the trademarked name of Irtran-6 but this is obsolete.
CdTe is also applied for electro-optic modulators. It has the greatest electro-optic coefficient of the linear electro-optic effect among II-VI compound crystals (r41=r52=r63=6.8×10−12 m/V).
CdTe doped with chlorine is used as a radiation detector for x-rays, gamma rays, beta particles and alpha particles. CdTe can operate at room temperature allowing the construction of compact detectors for a wide variety of applications in nuclear spectroscopy.[1] The properties that make CdTe superior for the realization of high performance gamma- and x-ray detectors are high atomic number, large bandgap and high electron mobility ~1100 cm2/V·s, which result in high intrinsic μτ (mobility-lifetime) product and therefore high degree of charge collection and excellent spectral resolution.

Physical properties

Lattice constant: 0.648 nm at 300K
Young's modulus: 52 GPa
Poisson ratio: 0.41
Thermal properties
Thermal conductivity: 6.2 W·m/m2·K at 293 K
Specific heat capacity: 210 J/kg·K at 293 K
Thermal expansion coefficient: 5.9×10−6/K at 293 K[2]
Optical and electronic properties

Fluorescence spectra of colloidal CdTe quantum dots of various sizes, increasing approximately from 2 to 20 nm from left to right. The red shift of fluorescence is due to quantum confinement.
Bulk CdTe is transparent in the infrared, from close to its band gap energy (1.44 eV at 300 K,[3] which corresponds to infrared wavelength of about 860 nm) out to wavelengths greater than 20 µm; correspondingly, CdTe is fluorescent at 790 nm. When the size of CdTe crystal is being reduced to a few nanometers and below, thus making a CdTe quantum dot, the fluorescence peak shifts towards through the visible range to the ultraviolet.

Chemical properties

CdTe has very low solubility in water. It is etched by many acids including hydrochloric, and hydrobromic acid, forming (toxic) hydrogen telluride gas and toxic cadmium salts. It is a reducing agent and is unstable in air at high temperatures.
Cadmium telluride is commercially available as a powder, or as crystals. It can be made into nanocrystals.


Cadmium telluride is toxic if ingested, if its dust is inhaled, or if it is handled improperly (i.e. without appropriate gloves and other safety precautions). Once properly and securely captured and encapsulated, CdTe used in manufacturing processes may be rendered harmless. CdTe appears to be less toxic than elemental cadmium, at least in terms of acute exposure.[4]
The toxicity is not solely due to the cadmium content. One study found that the highly reactive surface of cadmium telluride quantum dots triggers extensive reactive oxygen damage to the cell membrane, mitochondria, and cell nucleus.[5]. In addition, the cadmium telluride films are typically recrystallized in a toxic solution of cadmium chloride.
The disposal and long term safety of cadmium telluride is a known issue in the large scale commercialization of cadmium telluride solar panels. Serious efforts have been made to understand and overcome these issues. A document hosted by the U.S. National Institutes of Health[6] dated 2003 discloses that:
Brookhaven National Laboratory (BNL) and the U.S. Department of Energy (DOE) are nominating Cadmium Telluride (CdTe) for inclusion in the National Toxicology Program (NTP). This nomination is strongly supported by the National Renewable Energy Laboratory (NREL) and First Solar Inc. The material has the potential for widespread applications in photovoltaic energy generation that will involve extensive human interfaces. Hence, we consider that a definitive toxicological study of the effects of long-term exposure to CdTe is a necessity.
Researchers from the U.S. Department of Energy's Brookhaven National Laboratory have found that large-scale use of CdTe PV modules does not present any risks to health and the environment, and recycling the modules at the end of their useful life completely resolves any environmental concerns. During their operation, these modules do not produce any pollutants, and furthermore, by displacing fossil fuels, they offer great environmental benefits. CdTe PV modules appear to be more environmentally friendly than all other current uses of Cd.[7]
The approach to CdTe safety in the European Union and China is much more cautious: cadmium and cadmium compounds are considered as toxic carcinogens in EU whereas China regulations allow Cd products for export only.[8][9]

Pismo pulse picker
The Pismo pulse picker systems is as a pulse gating system that lets single pulses or group of subsequent pulses from a femtosecond or picosecond pulse train pass through the system, and stops other radiation. The system is perfectly suitable for most commercial femtosecond oscillators and amplifiers. The system can pick either single pulses, shoot bursts (patterns of single pulses) or pick group of subsequent pulses (wider square-shaped HV pulse modification). HV pulse duration (i.e. gate open time) is 10 ns in the default Pismo 8/1 model, but can be customized from 3 to 1250 ns upon request or made variable. The frequency of the picked pulses starts with single shot to 1 kHz for the basic model, and goes up to 100 kHz for the most advanced one.
The Pockels cell is supplied with a control unit that is capable of synching to the optical pulse train via a built-in photodetector unit, while electric trigger signal is also accepted. Two additional delay channels are available for synching of other equipment to the pulse picker operation. Moreover, USB connectivity and LabView-compatible drivers save a great deal of your time on storing and recalling presets, and setting up some automated experimental setups. One control unit is capable of driving of up to 3 Pockels cells, and this comes handy in complex setups or contrast-improving schemes. The system can also be modified to supply two HV pulses to one Pockels cell unit, making it a 2-channel pulse picker system. This may be essential for injection/ejection purposes when building a regenerative or multipass amplifier system.

AOTF Infrared Spectrometer
Del Mar Photonics offer a handheld infrared spectrometer based on the acousto-optic tunable filter (AOTF). This instrument is about the size and weight of a video camera, and can be battery operated. This unique, patented device is all solid-state with no moving parts. It has been sold for a wide variety of applications such as liquid fuel analysis, pharmaceutical analysis, gas monitoring and plastic analysis. Miniature AOTF infrared spectrometer uses a crystal of tellurium dioxide to scan the wavelength. Light from a light source enters the crystal, and is diffracted into specific wavelengths. These wavelengths are determined by the frequency of the electrical input to the crystal. Since there are no moving parts, the wavelength scanning can be extremely fast. In addition, specific wavelengths can be chosen by software according to the required algorithm, and therefore can be modified without changing the hardware. After the infrared radiation reflects off of the sample, it is converted into an electrical signal by the detector and analyzed by the computer. Del Mar Photonics is looking for international distributors for RAVEN - AOTF IR spectrometer for plastic identification and for variety of scientific and industrial collaborations to explore futher commercial potential of AOTF technology.

Femtosecond Transient Absorption Measurements system Hatteras Hatteras-D femtosecond  transient absorption data acquisition system
Future nanostructures and biological nanosystems will take advantage not only of the small dimensions of the objects but of the specific way of interaction between nano-objects. The interactions of building blocks within these nanosystems will be studied and optimized on the femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar Photonics, Inc. Thus we put a lot of our efforts and resources into the development of new Ultrafast Dynamics Tools such as our Femtosecond Transient Absorption Measurements system Hatteras. Whether you want to create a new photovoltaic system that will efficiently convert photon energy in charge separation, or build a molecular complex that will dump photon energy into local heat to kill cancer cells, or create a new fluorescent probe for FRET microscopy, understanding of internal dynamics on femtosecond time scale is utterly important and requires advanced measurement techniques.

Del Mar Photonics adaptive optics and wavefront sensors: ShaH-0620 wavefront sensor with telescope Wavefront Sensors: ShaH Family
A family of ShaH wavefront sensors represents recent progress of Del Mar Photonics in Shack-Hartmann-based technology. The performance of Shack-Hartmann sensors greatly depends on the quality of the lenslet arrays used. Del Mar Photonics. developed a proprietary process of lenslet manufacturing, ensuring excellent quality of refractive lenslet arrays. The arrays can be AR coated on both sides without interfering with the micro-lens surface accuracy. Another advantage of the ShaH wavefront sensors is a highly optimized processing code. This makes possible real-time processing of the sensor data at the rate exceeding 1000 frames per second with a common PC. Due to utilizing low-level programming of the video GPU, it is possible to output the wavefront data with a resolution up to 512x512 pixels at a 500+ Hz frame rate. This mode is favorable for controlling modern LCOS wavefront correctors.
The family of ShaH wavefront sensors includes several prototype models, starting from low-cost ShaH-0620 suitable for teaching laboratory to a high-end high-speed model, ShaH-03500. The latter utilizes a back-illuminated EM-gain CCD sensor with cooling down to -100°C. This makes it possible to apply such a wavefront sensor in astronomy, remote sensing, etc.

Frequency-stabilized CW single-frequency ring Dye laser DYE-SF-007 pumped by DPSS DMPLH laser installed in the brand new group of Dr. Dajun Wang at the The Chinese University of Hong Kong.
DYE-SF-077 features exceptionally narrow generation line width, which amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation line width of commercial lasers. Prior to this model, the narrowest line-width of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an acousto-optical modulator, which, as a rule, complicates the design and introduces additional losses. A specially designed ultra-fast PZT is used for efficient suppression of radiation frequency fluctuations in a broad frequency range. DYE-SF-077 will be used in resaerch of Ultracold polar molecules, Bose-Einstein condensate and quantum degenerate Fermi gas and High resolution spectroscopy
