Abstract
ZnSe thin films were deposited on a glass substrate by chemical bath deposition. The optical properties and annealing temperature at 250°C for 1 hour were observed, the results showed an increase in transmittance and an increase in the band gap. FESEM observations were performed at different magnifications (15,000, 30,000, 60,000, and 120,000X). ZnSe nanoparticles were distributed in various sizes (21–35 nm) and exhibited a spherical and quasi-spherical shape with a relatively uniform distribution. They were analyzed by XRD and revealed a polycrystalline structure; the results indicated that the samples exhibited a mixture of cubic and hexagonal structures. After annealing at 250°C, we observed an increase in the intensity of the plans, a slight shift in the diffraction angles, and a decrease in the average crystal size. The elemental composition of the ZnSe films using EDX revealed the presence of other elements such as Se, C, Zn, O, Si, S, Ca, Cl, Mg, and Na in varying percentage.
