Abstract
The scheelite BaWO4 materials were prepared by co-precipitation and molten salt method. The crystallographic structure, optical behavior, morphology, and electronic charge distributions of the prepared BaWO4 were studied by various spectroscopic techniques such as X-ray power diffraction, photoluminescence spectroscopy, UV–Visible absorption spectroscopy, scanning electron microscopy and electron density distribution analysis, respectively. The micron-sized rock-like structured BaWO4 particles were obtained in the surface morphology. These structured BaWO4 exhibited intense blue emission peak at 430 nm when excited at 375 nm. The synthesized material revealed the high intense blue emission which attributed to the intrinsic transitions of [WO4]2− tetrahedrons.
