説明Cadmium 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.
使用Cadmium 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.
一般的な説明CdSe 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
