摘要: Mg doped NiO nanoparticles MgxNi1−xO (x = 0, 0.1, 0.2, 0.3, 0.4) have been synthesized using sol–gel method. Their structure and morphology of the sample were analyzed X-ray diffractometer (XRD), transmission electron microscope (TEM) scanning (SEM) with energy dispersive spectrum (EDX). From XRD analysis, it is observed that can FCC a particle size 22 nm. Functional group analysis was carried out Fourier transform infrared spectroscopy (FTIR) Ultraviolet visible spectrometer. The obtained band gap 4.254 eV. Photoluminescence (PL) emission spectra showed blue strong at 345 nm. SEM TEM images confirmed spherical high crystalline nature samples. EDX purity magnetic properties samples vibrating magnetometer (VSM). 0.3 %Mg room temperature ferromagnetism higher saturation magnetization. used further for fabrication low cost counter electrode dye-sensitized solar cells (DSSCs). A thin film pure deposited on Fluorine tin oxide (FTO) coated glass substrate serves as an efficient plate to increase number holes induced electrocatalytic activity yield efficiency 2.4%.
