Abstract
Bi4BaxV2−xO11−δ (0.0 ≤ x ≤ 0.15) is synthesized by melt quench technique followed by sintering. The structural and optical properties of these samples are investigated using X-ray diffraction, Fourier transform infra-red (FTIR) spectroscopy and UV/vis spectroscopy. The γ-phase stabilization occurs at lower dopant concentration than as reported earlier for similar systems. The optical band gap is observed in the range of 1.5–2.0 eV. It shows decreasing trend with increasing dopant amount. FTIR bands become broader with respect to Ba2+ doping concentration.
