Synthesis, FTIR Studies and Optical Properties of Aluminium Doped Chromium Oxide Nanoparticles by Microwave Irradiation at Different Concentrations

Abstract

In this exposure zinc (Zn) doped chromium (III) oxide (Cr2O3) nanoparticles are synthesized by simple solvothermal microwave irradiation (SMI) technique. SMI technique is simple and low cost; it has the future to be produced on a huge scale. The effect of dopant (Zn) concentration on the structural behavior of Cr2O3 nanoparticles was examined by X-ray diffraction. The average crystallite size of the synthesized nanoparticles was measured from XRD patterns using Scherrer equation and was from ~14 nm to ~16 nm with the increasing Zn concentration in Cr2O3 from 0 to 5 % (in steps of 0, 1, 2, 3, 5). Almost uniform and hexagonal like morphologies and compositional elements of the synthesized nanoparticles were observed. The samples was analysed by photoluminescence and raman spectra. FTIR spectra of the samples were detected.
