Abstract

Nanowire array and film of cadmium sulfide were prepared by electroplating in organic solvent dimethyl sulfoxide with CdCl₂ and element sulfur under different temperature and current density. The UV-VIS absorption spectra show that increasing the electroplating temperature is benefit to forming perfect crystallites and the absorption peak under high electroplating temperature is ascribed to the excitonic transition. The formula of energy shift for the lowest several exci-tons is given and compared with the experiment. The photoluminescence spectrum consists of two parts: the first is pro-duced by recombination of the defects and the second by recombination of excitons.
