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.

Photoelectrode made of nanocable structure of ZnO nanorods (NR) coated with TiO(2) nanosheets (NSs) was investigated for CdS/CdSe quantum dot co-sensitized solar cells. ZnO NRs prepared solution reaction at 60 °C served as the backbone for direct electron transport in

We have recently synthesized atomically flat semiconductor colloidal nanoplatelets with quasi 2D geometry. Here, we show that core/shell nanoplatelets can be obtained with a 2D geometry that is conserved. The epitaxial growth of the shell semiconductor is performed at room

We describe the charge transfer interactions between photoexcited CdS nanorods and mononuclear water oxidation catalysts derived from the [Ru(bpy)(tpy)Cl](+) parent structure. Upon excitation, hole transfer from CdS oxidizes the catalyst (Ru(2+) → Ru(3+)) on a 100 ps to 1 ns
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
The electrochemical detection of cell lines of MCF-7 (human breast cancer) has been reported, using magnetic beads for the separation tool and high-affinity DNA aptamers for signal recognition. The high specificity was obtained by using the magnetic beads and aptamers
Selenium's roles range from essential dietary element to semiconductor in advanced applications like xerography.
