Facile Synthesis of BaWO₄Sub-Micron Sized Octahedron via a Microemulsion Method

Synthesis, Characterization, and Low Temperature Sintering of Nanostructured BaWO4for Optical and LTCC Applications

“…The absence of two modes and small discrepancy observed in the Raman-active modes when compared to early reports [37][38][39][40] may be due to the different preparation method, average crystal size, and structural disorder degree in the lattice. The absence of certain modes and activeness of modes at same regions of IR and Raman spectra points to the lowering of symmetry of crystal structure leading to short range distortion of crystal lattice which exactly corroborates with the XRD results.…”

“…Its other applications include nuclear spin optical hole burning hosts [6], radiation detection [1], scintillating devices [4], and other electro-optic applications [1]. Since the properties of materials can be tuned by its microstructure, different morphological BaWO 4 such as nanowires, spheres, cylinders, whiskers, penniform BaWO 4 nanostructures, and flower-like structures were prepared [18][19][20][21][22][23] and methods like solid-state reaction [24][25][26], hydrothermal-method [9,[27][28][29], Czochralski [30][31][32][33], high temperature flux crystallization [34], polymeric precursor chemical route [35], microwave-assisted synthesis [36,37], and micro emulsions-based routes [19,38] were employed for the synthesis.…”

Visible Light Photocatalytic Degradation of Methylene Blue and Malachite Green Dyes with BaWO4-Go Nano Composite

“…The optical properties of pure BaWO4, nano BaWO4 and BaWO4-GO composite were evaluated by UV-diffuse reflectance spectroscopy, shown in Fig 5. The optical absorbance spectra for BaWO4 nanoparticles and BaWO4-GO appeared in the ultraviolet region 285nm, by introducing graphene oxide on the surface of nano BaWO4, there was a similar absorption edge with nano BaWO4, indicating that the graphene oxide was not incorporated into the lattice of BaWO4 and just got adsorbed on its surface [32]. It was reported that absorption is a powerful, nondestructive technique to explore the optical properties of sample.…”
