چکیده

In this article, ZnO and ZnO:Mn nanoparticles prepared by reverse micelle method. The various crystalline properties of these nanoparticles such as size, d-spacing, strain, stress, dislocation density and texture coefficient have been calculated with the help of XRD spectrum. The XRD results indicated that the synthesized ZnO and ZnO:Mn nanoparticles have a pure wurtzite (hexagonal phase) structure. It can be seen that the highest texture coefficient was in (002) plan for nanoparticles. The optical band gap energy of ZnO and ZnO:Mn nanoparticles have been analyzed by using UV-Vis data. The photoluminescence spectra of the nanoparticles indicated their high structural and optical quality.
