A nanocrystallineCdS film can be deposited by chemical bath deposition using non aqueous medium. XRD analysis confirms the crystalline structure of CdS (002) with 34 nm crystallite size. The as deposited films are stoichiometric in nature with Cd and S atomic % ratio equal to 1.0. The field emission scanning electron miceoscope and atomic force microscopy studies revels a densely packed non porous granular deposit with RMS value of roughness equal to 92nm. The band gap of the film is measures by spectroscopy and it is observed to 2.40 eV which is good agreement with the reported result. The photoluminescence prominent peak of the CdS film is observed to be 392 nm.
