Low temperature photoluminescence studies on sputter deposited cadmium sulphide/cadmium telluride heterojunctions and solar cells
… is thought to be either due to Cu occupying cadmium vacancies (VCd) or forming acceptor complexes with them. This points to a potential role of Cu in plugging sub-band gap recombination routes and hence increasing charge separation ability of the device. An energy band diagram is presented …

Synthesis and surface modification of nanorods for investigation into organic-inorganic hybrid materials
… semiconductors.Several syntheses of gold and cadmium sulphide nanorods were performed and optimised in order to increase the yield, aspect ratio and monodispersity of nanorods formed. Localised alignment according to Onsager theory was observed for nanorods produced with sufficient aspect …

Application of Pulsed D.C. Magnetron sputtering deposition for the component layers of CuInSe2 thin film photovoltaic cells
… back contact layer, aCIS absorber layer, a cadmium sulphide buffer layer and a zinc oxide top layer. In this study,toxic cadmium sulphide was replaced by indium sulphide and the top layer employed indiumoxide which could be changed from intrinsic to highly conducting by adjustment of …

Some factors affecting the temperature coefficient of zinc sulphide type phosphors
… of the intensity (B) with temperature for zinc sulphide type phosphors continuously excited ultra-violet radiation. The way in which the temperature coefficient of the phosphors depends on the silver and nickel concentrations is discussed. It is also shown that the temperature coefficient …

Luminescent Harnessing of 2D Transition Metal Dichalcogenide Excitons
… reported schemes, is applicable to both sulphide and selenide TMDs. As separate studies, we investigate the effects of OA on monolayer tungsten disulphide (WS2) and molybdenum diselenide (MoSe2). Steady state and time resolved PL (TRPL) microscopy uncover the photophysics of PL …

Plastic and mixed waste as feedstocks for solar-driven H₂ production
… and noble-metal-free photocatalysts is reported. Cadmium sulphide quantum dots are first shown to generate H₂ and a range of organic oxidation products from polar polymers and food components following a low-temperature pre-treatment step under alkaline conditions. In order to develop a less toxic …

Electrodeposition of semiconductors for applications in thin film solar cells
… method were to be used for commercialisation. Cadmium telluride (CdTe) was electrodeposited from aqueous solution onto glass/fluorine doped tin oxide/cadmium sulphide substrates. Little improvement in XRD spectra was observed for annealed layers compared to the as-deposited material and the …

Structural, electronic and optical properties of cadmium sulfide nanoparticles
… linear-response theory have been performed on cadmium sulfide nanoparticles considering different stoichiometries, underlying crystal structures (zincblende, wurtzite, rocksalt), particle shapes (spherical, cuboctahedral, tetrahedral), and saturations (unsaturated, partly saturated, completely …
