Microwave-assisted solvothermal synthesis and characterization of barium orthovanadate nanoparticles

Abstract

Barium orthovanadate (Ba3V2O8) nanoparticles were synthesized successfully using a facile microwave solvothermal route followed by further heat-treatment. Well-crystallized Ba 3V2O8 nanoparticles were formed after heat-treatment at 600 °C for 3 h showing a fine and homogeneous morphology with particle sizes of 50-150 nm. The synthesized Ba3V 2O8 nanoparticles were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. The optical properties were investigated by photoluminescence emission and Raman spectroscopy.
