Efek Dopan Mangan (Mn) Terhadap Struktur dan Sifat Optik Nanopartikel Zn1-xMnxO

Abstract

The Zn1-xMnxO nanoparticles have successfully been synthesized by coprecipitation methods. The research was conducted by using Zinc Acetate Dihydrate powder, Mangan powders were employed using HCl and NH₄OH as the solvent and precipitating agents respectively. Synthesis of Zn_1-xMn_xO nanoparticles was carried out with the variation of Mn doping (x = 0 - 0,03) in the precursor solution. Structural characterization using X-Ray Diffractometer (XRD) and Scanning Electron Microscopy (SEM) was then performed. From XRD data analysis, the Zn_1-xMn_xO crystal size decreases with increasing of Mn ion dopant. While testing the optical properties using Genesys 10S Spectrophotometer UV-vis then the transmission spectrum obtained is processed to obtain the optical band gap. The results show that the increasing of Mn dopant ion in Zn_1-xMn_xO nanoparticles decreases the gap energy (Eg) Zn_1-xMn_xO.
