General description

Natural occurrence: hawleyite (structural type of sphalerite) and greenockite (structural type of wurtzite)

Application

Applications: pigment in the chemical industry; photoresistors; optical-electronic pairs, photodiodes, solar batteries; phosphors. Single crystals of cadmium sulfide are used for the preparation of optical devices operating in the infrared regaion of spectrum. Cadmium sulfide is a direct band gap semiconductor with a band gap band from 2.42 to 2.57 eV.
CdS nanowires were synthesized from CdS powder.

We describe the synthesis of cadmium bis(diphenyldithiophosphinate) (Cd(S(2)PPh(2))(2)) from secondary phosphine sulfides and its conversion to cadmium sulfide nanocrystals. Heating Cd(S(2)PPh(2))(2) and cadmium tetradecanoate (≥4 equiv) to 240 °C results in complete conversion of Cd(S(2)PPh(2))(2) to cadmium sulfide nanocrystals with

Ultralow-threshold two-photon pumped amplified spontaneous emission (2ASE) and lasing in seeded CdSe/CdS nanodot/nanorod heterostructures is demonstrated for the first time. Such heterostructures allow the independent tunability of the two-photon absorption (2PA) cross-section (σ(2)) through varying the CdS rod size, and
