| Abstract | ||
| In this research was to study the effect of Doping manganese Mn Morphology and optical properties of zinc sulfide ZnS thin films , ZnS films were deposited on glass substrates using technology pulse laser Deposition (PLD) under vacuum (10-3 Torr) and the conditions of preparation included substrate temperatures (400 0C), Oxygen pressure (0.1 mbar) and laser energy (700 mJ) using a pulsed (532 nm) Nd:YAG laser , And has a Dope agent by mixing the substance to be Doping (ZnS) with the ratio of grains of impurities (Mn) . Select the topographic properties of films using scanning electron microscope (SEM) and atomic force microscope (AFM), respectively for the purpose of screening surfaces of thin films , And we found that the structural of polycrystalline films , While Optical properties of the films were determined from the transmittance data using Swanepoel model And less increase Doping rates , Transmittances of film were measured by spectrophotometer. noted that the absorbance increases with increasing Doping rates Up to (0.8) , While optical energy gap of at least (3.3-3.6 eV) when ratios Doping (0 - 1.5 Mn%) on the respectively . | ||
