Abstract

The Erbium doped magnesium oxide nanoparticles (Er-MgO NPs) have been synthesized in the form of crystalline powder using the chemical precipitation method and the structure was confirmed by Photoluminescence (PL), Fourier transforms infrared spectrophotometer (FT-IR), Powder X-ray diffraction (PXRD), Scanning electron microscope (SEM) coupled with Energy Dispersive X-ray Spectroscopy (EDX). Furthermore, dielectric properties and antibacterial activity were tested. The stretching frequency in the FT-IR spectrum confirms the metal-oxygen bond Er-MgO-NPs. The SEM image reveals spherical-shaped particles with agglomeration. The EDX spectrum confirms the elemental composition (Er and O) present in the synthesized sample. The Vibrating Sample Magnetometer (VSM) graph shows that the doped MgO nanoparticles exhibit paramagnetic behaviors at room temperature. The frequency dependence of dielectric constant, dielectric lossand ac conductivity were studied over a range of the frequency 42Hz to 5MHz at room temperature.
