개요

Zinc selenide (ZnSe) is an II-VI compound semiconductor material with a face-centred cubic crystal structure and excellent physicochemical properties, which has a wide range of transmittance, from 0.5 microns to 19 microns. Zinc selenide is a very good infrared material, mainly used in infrared optics and optoelectronics, and can be used to manufacture window materials, focusing lenses, beam splitters, prisms, and CO2 lasers. Zinc selenide is also commonly used as lenses and windows for CO2 lasers due to its good imaging and thermal shock properties.

화학적 성질

Zinc selenide(ZnSe) is a yellow shiny fine powder that rarely occurs in nature. It is a chemically inert, non-hygroscopic and highly pure material largely found in the mineral stilleite. The transmissivity of zinc selenide is relatively constant over the wavelength range between 0.7 × 10 -6 to 16 × 10 -6 m, making it an excellent choice for flare radiation measurement. ZnSe is highly transparent to the radiation emitted from a flare flame. It is effective in many optical applications owing to its high resistance to thermal shock, stability in virtually all environments and extremely low bulk losses.

용도

Zinc selenide (ZnSe) is used as an infrared optical material with wide transmission wavelength range. It is also used as an entrance optic in the new range of "in-ear" clinical thermometers. ZnSe is used as a semiconductor material for thin film devices, and n-type windows layer for thin film heterojunction solar cells. ZnSe activated with tellurium is a scintillator suitable for matching with photodiodes. It is used in x-ray and gamma ray detectors. Zinc selenide films are useful in photovoltaic cells and solar conversion cells. The material can be doped with n-type and p-type doping. It is used to form light-emitting diodes and diode lasers. ZnSe doped with chromium finds use as an IR laser gain medium.

공기와 물의 반응

ZnSe is insoluble in water, but reacts with acids to form toxic hydrogen selenide gas. It can be deposited as a thin film by chemical vapour deposition techniques including MOVPE and vacuum evaporation.

위험도

Fire risk in contact with water or acids.

Synthesis

Zinc Selenide is produced by synthesis from Zinc vapour and H2Se gas, forming as sheets on Graphite susceptors. Another method of producing is a growth from melt under excessive pressure of inert gas (Ar usually).
