Using solid state reactoin method, Tungsten double perovskite oxides Ba2NiWO6 have been prepaired. The X ray diffration XRD, Scanning electronic microscopy SEM, Ultravielot.visible diffuse reflection, Photoluminescence spectra and Electrical impedance spectroscopy were used to charactrize the structure and optical properites of the synthesized material. From X ray powder diffration examination, the sample shows a cubic structure with (Fm-3m) space group, and the lattice parameter was investgated using Retvield method that found to be 8.10875 Angestrom. The band gap energy of Ba2NiWO6 estimated to be 3.20 eV from the diffuse reflection spectrum. At room temperature the excitation and emission photolumenescence and EIS have been investgated. |
