The Optical properties of Cadmium Stannate (Cd2SnO4) Thin Films Prepared by Chemical Spry Pyrolysis Technique
MetadataShow full item record
Thin films of cadmium stannate were prepared using thermal chemical spray pyrols: Cadmium stannate' solution (0.2M) was prepared by dissolution of CdCl25H2O in C2H5OH tion of SnCl23H2O in CH3COOH at molar 2:1, respectively. The Cd2Sn04 solution was spra substrate that was kept at 300°C. The studies of structure showed that the prepared thin film phous. After annealing, no changes observed in the films' structure. The type of electronic t determined by studying the Ultra Violet/Visible (UV/Vis) spectrum. Energy's gap, width of lo tail, refraction coefficient, reflection index, and extinction coefficient were calculated bef annealing. The optical constants were increased by increasing annealing's temperature and ness.
