Synthesis and characterization of Selenium Doped Zinc Oxide (ZnO-Se) Nanoparticles

In this study ZnO nanoparticles were synthesized by using different procedures. In the first procedure ZnO prepared by using sol-gel method by precipitating ZnO from a reaction of Zinc nitrate (Zn(NO3)2) and Sodium hydroxide (NaOH) different techniques are used sol-gel method with stirring and centrifugation to obtain ZnO nanoparticles. In the second procedure grinding of Zn(CH3COO)2 and H2C2O4.2H2O in a mortar for 30 min is used, also by doping Selenium powder (5%) to the mixture and ZnO-doped Selenium was obtained. ZnO nanoparticles were characterized by X-ray (Rajendra et al., 2009) diffraction (XRD) where diameter ranged between 16-33 nm by using Scherrer equation. d-space (d) was calculate theoretically by using Bragg’s law and practically by the formula. Some lattice also were calculated and showed in the tables like: micro strain (ε), potential parameter (μ), bond length (L), unit cell volume (V) and stress (σ).
