3–12mm pieces (sintered), and -325 mesh 10μm or less with 99.999% purity; white to brown; cub or hexagonal crystal(s); hex: a=0.4309nm, c=0.7021 nm, enthalpy of fusion 305.307 kJ/mol; becomes red in sunlight; used as a red pigment, in semiconductors, and as an evaporation material and sputtering target to produce photoconductive films and infrared filters; possible use in the electrofabrication of microdiode arrays [HAW93] [MER06] [CER91] [KLE93] [KRE91]

개요Cadmium selenide (CdSe) appears as grayish-brown or red crystals, is insoluble in water, highly toxic, and has a melting point of 1350°C. It can be produced by co-heating metallic cadmium with hydrogen selenide and is used in electron emitters, spectral analysis, photoconductors, semiconductors, and photosensitive components.

용도Cadmium selenide is used as a n-type semiconductor and its nanoparticles are used in laser diodes, opto-electronic devices, nanosensing, biomedical imaging and high efficiency solar cells. Since, it is transparent to infrared light, it finds application in photoresistors and windows for instruments utilizing IR light.

일반 설명CdSe crystal can exist in solid hexagonal or cubic structure. CdSe behaves as an n-type semiconductor, with a bandgap of 1.74 eV (300K).1
