Abstract

Polycrystalline CdS films wer eobtained by a micro-controlled SILAR deposition technique,usingaqueou solutions of cadmium acetate and thiourea a sprecursors. Th estructural and optical properties of the films were found to be influenced by various deposition parameters such as number of immersion cycles,concentration of the precursors and temperature of the solutions.Contrary to the observations made by some researchers,we found that the thickness of the films increased continuously with number of immersion cycles and also with concentration of the precurs or solutions.We also found that the films covered the substratesuniformly,without any voids,unlike the films obtained by others.Effect of deposition parameters on thickness,substrate coverage,grainsize,chemical composition,opticalband gap and other properties of the films is discussed indetail.
