Abstract

Enhancement of the luminescence intensity and persistent emission of ZnTa₂O₆:Pr³⁺ phosphor was achieved by preparing it in the presence of Li₂SO₄ and Li₂CO₃, which act as flux agents. The flux agents had an effect of increasing Pr³⁺ formation as shown by the X-ray photoelectron spectroscopy, which reinforced the luminescence intensity. Additionally, they enhanced the electron trapping centres as shown from the thermoluminescence spectroscopy data, and therefore enhanced the persistent luminescence.
