Structural and Optical Analysis of Eu³⁺ Doped BiVO₄ Nanophosphor by Combustion Method

Abstract:

Present article report synthesis and spectroscopic analysis of BiVO₄ nanophosphor doped with trivalent Eu ions. It was observed that BiVO₄ nanocrystals shows higher yield in comparison with the as-made nanocrystals on 266 nm laser excitation. On 266 nm excitation, emission composed of red dominated wide spectrum in the range of 400-950 nm was reported. Emission intensity enhanced five times on annealed sample than the counterpart. Time resolved analysis explores significant alteration in excited state relaxation process due to annealing. Detailed photo physics involved to improve optical emissions has also been explained.
