Cadmium sulphide (CdS) thin films were deposited on glass substrate by chemical bath deposition(CBD). The films were annealed in air at 300°C for one hour. Both the as-deposited and annealed films were characterized by XRD, UV-visible spectrophotometer, EDAX and Photoluminescence study. A mixed phase of hexagonal and cubic structure of the as-deposited film was confirmed by XRD. On annealing, the films were confirmed to be purely hexagonal. A band gap of 2.35 eV of the as-deposited films and 2.29 eV of the annealed films were derived from UV-VIS spectral data. Photoluminescence (PL) spectrum exhibits green and redemission peaks. EDAX spectral analysis reveals composition of the film before and after annealing.
