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.

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

The novelty and potential of self-assembled superstructures reside not only in the more commonly investigated optical, magnetic and charge transport properties, but also in their mechanical behaviour, which is strictly dependent on their structural morphology. We report here nanocompression tests

A facile method for synthesis of CdS nanoparticles has been described. Monodisperse face-centered cubic CdS NPs could be synthesized in switchable surfactant reverse micelles. The micelles could be broken easily and CdS NPs without a coating of surfactants could be

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
