Abstract
Undoped and Mg-doped ZnO nanoparticles were synthesized by co-precipitation method. The synthesized nanoparticles are successfully characterized by XRD, SEM, and UV-visible analysis. The Structure, Morphology, and Optical activity of the synthesized nanoparticle were studied with respect to ZnxMg1-xO (where x= 0, 2.5%M and 7.5%M). The XRD patterns revealed the wurtzite structure for all the nano samples. XRD studies confirmed that the crystalline size increased with increase in Mg content. The surface morphology of the prepared pure and Mg doped ZnO nanoparticles are investigated by SEM analysis. Optical characterization reveals that band gap energy decreases from 3.24 to 3.13 eV with Mg doping. UV-Visible results revealed that absorption underwent a red shift with Mg into ZnO as compared to pure ZnO.
