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


In this paper, the ZnO thin films have been prepared by spray researchthickness (300nm) on a glass substrates and studying its optical and electric properties. The results of (X-Ray ) diffraction showed that the films have a polycrystalline structure , The Absorption and The transmission as a function of photon energy for ZnO films had been studied. The Investigation of energy gap of the direct allowed transitions of ZnO film showed a value of (3.14 eV). The optical Absorption coefficients have been studied as a function of PhotonEnergy See beck measurements revealed that ZnO thin films are n-type.
