Abstract

Cathodic electrodeposition in the presence of sodium dodecyl-sulphate in aqueous solution was used to prepare CuSe thin film deposited on titanium substrates. The effect of deposition potential, concentration and deposition time were studied to determine the optimum condition for the electrodeposition process. The films were characterized by X-ray diffractrometry. Scanning electron microscopy was used to study the morphology of the deposits. The photoresponse of the films prepared was analysed using linear sweep voltammetry in the presence of sodium thiosulphate.
