| Abstract | ||
| Effects of substrate temperature on the microstructure, morphology, and optical properties of ZnS thin films were investigated. ZnS films were deposited on glass substrates by pulsed laser deposition at different substrate temperatures using a pulsed 532 nm Nd:YAG laser is presented . The structure and morphology of the film were studied by X-ray diffraction and atomic force microscopy, the average surface grain size and RMS surface roughness of the films increases with increasing substrate temperature. Optical properties of the films were determined from the transmittance data using Swanepoel model,Transmittances of film were measured by spectrophotometer. Additionally, the increase of the substrate temperatures increase the pores and the transmittance in the films, it was observed that the energy band gap is increased from 3.4 eV to 3.6 eV of the films are decreased with the increase of substrate temperature . Moreover , considerable improvement in blue response of the films was noticed with increasing substrate temperature . | ||
