Abstract
The synthesis of magnesium doped Tungsten oxides (Mg:WO3) nanomaterial was achieved using a simple household microwave irradiation method. In which 3 and 10 wt% magnesium chloride were used to prepare the above material. The synthesized materials were structurally and optically characterized using various techniques like X- Ray Diffraction, FTIR, UV-DRS, PL and SEM-EDAX. The X-ray diffraction confirms clearly showed the presence of crystalline Mg: WO3 particles. Further, UV-DRS and FTIR result shows the presence of Mg: WO3 nanomaterials at specific wavelength. From UV-DRS the optical band gap energy increases to 3–3.15 eV compare to the pure materials. The scanning Electron Microscopy(SEM) analysis conforms that the synthesized Mg:WO3 was spherical in shape and has 30–40 nm size in diameter. EDAX confirms the Mg doped in the synthesized material. The emission spectra of the undoped and Mg doped samples were analyzed using PL spectroscopy.
