Abstract

Nanocrystalline BaMoO 4 was synthesized through auto-ignited combustion technique. The X-ray diffraction studies of BaMoO 4 nanoparticles reveals that the as-prepared powder is single phase, crystalline, and has tetragonal structure. The average particle size of the as-prepared powder from transmission electron microscopic is found to be 22nm. The thermal stability of the nano powder was examined using thermo gravimetric analysis and differential thermal analysis. The band gap determined from absorption spectra is 3.20eV.Photoluminescence spectra of the samples shows green emission peak. The dielectric constant and loss factor of the sample at 1 MHz is found to be 9.75 and 1.38×10 −2 at room temperature.
