【 摘 要 】

A solid-state metathesis approach initiated by microwave energy has been successfully applied for the synthesis of orthovanadates, M₃V₂O₈ (M = Ca, Sr, and Ba). The structural, vibrational, thermal, optical and chemical properties of synthesized powders are determined by powder X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, magnetic property measurements and diffused reflectance spectra in the UVâ€�?�VIS range. The direct bandgap of the synthesized materials was found to be 3.55 ± 0.2 eV, 3.75 ± 0.2 eV and 3.57 ± 0.2 eV for Ca₃V₂O₈, Sr₃V₂O₈ and Ba₃V₂O₈, respectively.
