A comparative investigation on the optical conductivity of Mg and Sn doped ZnO nanoparticles in UV regime

Year: 2025

Type: article

Abstract: This study investigates the optical properties of zinc oxide (ZnO) nanoparticles, doped with Mg and Sn, to enhance optical conductivity in the UV regime. ZnO was synthesized via co-precipitation, and structural analysis confirmed the retention of its hexagonal wurtzite structure. Using scanning electron microscopy and energy dispersive spectroscopy, morphological and elemental analysis of the synthesized nanoparticles were studied, respectively. Optical analysis via UV-vis-NIR spectroscopy revealed a blue shift in absorbance, indicating an increase in bandgap with higher doping concentrations. The results show that small Sn doping enhances optical conductivity more effectively than higher Mg doping.
