| Abstract | ||
| In this work, CdSe thin films have been prepared by chemical bath deposition on glass substrates using and as a source of and respectively, with a solution concentration 0.5M, a solution temperature at 70oC, pH=9 and deposition time 3 hours. The doping process was carried out with tin Sn and copper Cu with different amounts 0.5%, 1%, 1.5% also by CBD. The XRD studies show that the pure and the doped thin films were polycrystalline and cubic structure in the (111) plane direction, (220) and (311) too. SEM technique used to identify the surface nature of CdSe thin films as well as the average crystal size of the growing grains was (5.9nm). The images show a spherical grain, microcode, and other floral shapes with Cu doping at 70oC. | ||
