STRUCTURAL AND THERMAL STUDY OF RUTHENIUM AND INDIUM DOPED CDSE THIN FILMS

In present work, Ruthenium and Indium doped Cdse thin films were synthesized using the chemical bath deposition Technique on the fluorine doped tin oxide (FTO) substrate. The crystal structure and surface composition of the doped CdSe thin film are obtained by X-ray diffraction patterns, energy dispersive X-ray analysis, and FE-SEM images. The optical properties of obtained films were characterized by UV-visible spectral analysis. The UV- visible study reflects the transmittance and band gap in the range of 1.65 to 1.75 eV. Thermogravimetric analysis of doped CdSe in temperature region from zero to 1000 ⁰C confirms the weight loss of 10 % in the range from 200 to 250 ⁰C due to the removal of water contents from the film surface.
