Cadmium sulfide (CdS) is a wide-gap semiconductor. Its properties change
substantially upon the transition from macro-sized samples to nano-structured state. For instance, the bandgap of CdS single crystals at room temperature is 2.4 eV but can reach up to 4.5 eV for CdS nanocrystals. CdS nanoparticles exhibit nonlinear dependence of luminescence emission frequency on the particle size, and thus can be used as quantum dots for biological object imaging and development of new optoelectronic devices. Additionally, unique photoconductivity and luminescent properties make CdS a material for manufacturing injection lasers, solar cells, photosensors, photoresistors, scintillation detectors of elementary particles and γ-radiation etc. Therefore, the purpose of this work is to investigate the effect of chemical composition and temperature of the electrolyte on the synthesis of nanoparticles of cadmium compounds, including CdS.
