| Abstract | ||
| In this study, the effect of substrate temperature on structural, morphological and optical properties of CdS thin films deposited by spray pyrolysis is investigated. XRD analysis revealed that the deposited CdS films are polcrystalline in nature with perferential orientation of (100)(002)(101)(220) (311) plane. The grain size increases as deposition temperature increases. Atomic Force Microscopy(AFM) investigation showed that the deposited film contains columnar growth and the average grain size were (125.75nm, 104.45nm) and the root mean square of roughness were (7.01 nm, 8.35 nm) at Ts=300°C and 400°C respectively. The optical properties of nanostructure CdS films are strong depedence on substrate temperature. The band gap(Eg) of the CdS films deposited at Ts=300,350 and 400°C was found to be (2.38 ,2.44 ,2.41 eV) respectively. | ||
