Study of some optical Properties of PbS thin films deposited by Chemical Spray Pyrolysis Method

Abstract

In this research we prepared ZnO thin films by Spray pyrolysis method withthickness (300nm) on a glass substrates and study its optical and electric properties.The results of (X-Ray ) diffraction showed that the films have a polycrystallinestructure , The Absorption and The transmission as a function of photon energy forZnO films had been studied , The investigated of energy gap of the direct allowedtransitions of ZnO film showed a value of (3.14 eV). The optical Absorptioncoefficients have been study as a function of Photon Energy.See beck measurements revealed that ZnO thin films are n-type.
