Using thermal evaporation, thin films of silver-doped CdSe were synthesized on glass bases. A hexagonal structure with a preference orientation along (100) plane according to the X-ray diffraction pattern. The surface topography was determined using Atomic Force Microscopy (AFM). AFM detects spherical nature nanoparticles and roughness rate of the CdSe thin film decreases and the root mean square decreases with (2 and 4) % doping in silver. As the doping content increase, the optical energy bandgap decrease from 1.85 eV to 1.75 eV. Optical analysis indicates that Ag doping in CdSe results in a redshift in band edge.
