Abstract

Silver thin films due to its tremendous applications in different fields; have been attracted by scientists and researchers. In this theses, homogeneous silver thin films have been prepared by sputtering technique and also inhomogeneous silver thin films prepared by same method with the help of shadowing process and their optical, structural and wetting properties have been investigated by of UV-Visible spectroscopy, Scanning Electron Microscope(SEM), Diffuse Reflection Spectroscopy(DRS), X-ray Diffraction (XRD) and imaging of contact angle. The comparative results of optical characteristics and wetting properties confirms each other and it is observed that by increasing in height of shadow, the amount of contact angle of the surface of thin films increases. Also obtained results from Bruggman homogenization theoretical method have a good agreement with experimental results.
