  • Abstract

    Thin film of CdSe has been deposited onto clean glass substrate by using Chemical Bath Deposition technique. For the as-deposited films, the XRD analysis revealed a uniform cubic phase of CdSe nanocrystalline thin film with preferred orientation along the (111) plane. Absorption spectra of this film have been recorded using spectrophotometer. The thickness of the film has been determined by gravimetric method. The energy band gap has been calculated using Tauc method. It is found that energy band gap of CdSe film is 2.35 eV.
