Abstract
Cd–Se thin films of varying thicknesses were prepared on glass substrate by chemical bath deposition technique at room temperature in which selenium dioxide is source of Se2− while cadmium acetate is source of Cd2+ ions. Ammonia was used as complexing agent. Nickel doping is achieved by adding Ni(NO3)2 solution to the bath. Approximate thickness was measured by gravimetric method. Band gap of the films was determined by measuring percent transmittance of film at various wavelengths. The band gap and thickness of the film were found to increase with increase of Ni concentration in films. The composition and structural characterization was carried out by using EDAX and SEM.
