Cadmium Selenide (CdSe) Nanoparticles
Cadmium selenide (CdSe), which is also known as cadmoselide, is a binary compound of cadmium and selenium. It is an inorganic solid material with an oxblood color and usually provided in powder form. Three different crystalline forms of CdSe are; wurtzite (hexagonal), sphalerite (cubic), and rock-salt (cubic).The sphalerite CdSe structure is unstable and converts to the wurtzite form upon moderate heating while the rock-salt structure is only observed under high pressure. CdSe nanoparticles have received a lot of attention because of their unique optical and electronic properties. It has attracted attention as an n-type semiconducting material. The tunable bandgap of CdSe makes it an attractive candidate for the fabrication of tunable light absorbers and emitters in LEDs, quantum-dot lasers, and optical probes in biological staining and diagnostics. CdSe can also be used as an efficient electron acceptor in the composites with various conjugated polymers.
