Zinc Selenide nanoparticles have been synthesis on glass substrate by chemical bath deposition. The optical properties were investigated and the annealing temperature at 250C for one hour on the transmittance spectra and the energy bad gap were observed, transmittance was gradually decreased and band gap was increased. The samples were measured by FESEM, XRD pattern and EDX. FESEM at various magnification powers (15 000, 30 000, 60 000 and 120 000 X) ZnSe films have been viewed. ZnSe nanoparticles were distributed with different sizes (26.61 – 41.50 nm) and they were taken the form of nanosheets. ZnSe prepared samples were analyzed by XRD and they were exhibited polycrystalline structure; the results were showed that the samples have been mixture of cubic and hexagonal structure. After annealing at 250C, we observed that the intensity of planes is low, a small shift in the diffraction angles and average crystal size was decreased. From elemental compositional of ZnSe films by EDX, the distinctive peak was due Zn element at 1 KeV and the appearance other elements such as Se, C, N, O, Si, S and Ca with different percentage. |
