Exploring the effect of boron on the grain morphology change and spectral properties of Eu³⁺ activated barium tantalate phosphor

Abstract

The effect of the grain morphology on the photoluminescence, charge transfer band, and decay properties was investigated by xEu3+, yB3+ (x = 10 mol%, y = 0, 5, 15, 30, 50, 70, and 100 mol%) co-doped BaTa2O6 ceramics fabricated by solid-state reaction.
