Structural And Optical Properties Of Zno Nano-powder Synthesized By Combustion And Sol-gel Method

Abstract Nowadays, ZnO is considered as the most important chemical compounds due their distinctive properties owing to its wide band gab and large exciton binding energy. It is well known that the structural and the optical properties of ZnO differ by different methods of preparation. Therefore, in this work, ZnO power was prepared by two methods, namely sol-gel and combustion method with the aim of comparison. The obtained samples from both methods were investigated by many techniques for considerable comparison. The obtained results from ZnO synthesized by the sol- gel method showed that th…
