Mg Doped on ZnO to Investigate the Effect of Mg Ions on optical properties and bandgap of ZnO Nano-particle

Abstract

In this study, the optical (absorption coefficient and transparency) properties and the energy band of Zinc Oxide nano particles doped with magnesium ion were investigated within different weight percent namely (0.00 , 0.05 and 15% of weiht) was synthesized , the ZnOnano particles was prepared using sol–gel method. A UV-VIS spectrophotometer used to investigate the absorption coefficient and transparency of ZnO nanoparticles with each weight percent adding of magnesium ion, The results indicates that the transmittance has a tendency to decrease with Mg progressed, , the results also show that Absorption coefficients in the UV region significantly increased with Mg progress and due to tauc equation the bandgap of ZnO nanoparticle can be change as Mg progressed.
