Abstract

Cathodic electrodeposition in the presence of tartrate ions as complexing agents in aqueous solution was used to prepare cadmium sulfide thin films deposited on titanium substrates. The effect of deposition periods and solution temperatures towards the crystallinity of the cadmium sulfide thin films were investigated. The thin films were characterized using X-ray diffractometry. The absorption properties, band gap energy and transition type was determined using UV-Vis Spectrophotometry. The thin films produced were polycrystalline in nature. The films showed good adherence towards the substrate in the presence of sodium tartrate. The band gap value was found to be 2.3 eV with direct transition.
