چکیده انگلیسی
Structural properties of electrodeposited ZnSe thin films were studied using X-ray diffraction (XRD) and the electrodeposited films are found to be polycrystalline in nature with face centered cubic structure. Optical constants of ZnSe thin films for various deposition potentials were determined in the spectral range 400-1200Â nm using the optical absorption and transmittance measurements. The Tauc's plot was drawn to determine the energy band gap values of the deposited films and is estimated to be in the range between 2.52Â eV and 2.61Â eV respectively. Their optical constants like refractive index (n), dielectric constants (É), optical conductivity (Ï), average excitation energy (E0), oscillator strength (Ed), effective mass (m*), plasma frequency (Ïp), static dielectric constant (Éâ) and carrier concentration (N) were estimated and reported. The room temperature photo luminescence studies were also performed. The near band edge luminescence emission has been observed and reported.
