Abstract
The good optical and chemical properties of Ba3Gd(PO4)3 (BGPO) make it an attractive option for use as an optical material. In this study, photoluminescence (PL) and thermally stimulated luminescence (TSL) properties of Dy-doped BGPO single crystals were investigated. The floating zone furnace was utilized to fabricate the bulk Dy-doped BGPO single crystals. Out of all the prepared Dy-doped BGPO single crystals, the 10 % Dy-doped sample exhibited the highest PL quantum yield value. All the prepared Dy-doped BGPO single crystals showed PL and TSL peaks at 310, 480, 580, 670, and 760 nm, resulting from 4f-4f transitions of Gd3+ and Dy3+. The PL decay profiles had one component with a decay time constant of approximately 0.9 ms in all the prepared Dy-doped BGPO samples. The TSL glow peak of all the prepared Dy-doped BGPO samples located at 75 ℃. The 5 % Dy-doped BGPO sample displayed the highest TSL intensity with the lower detection limit of 0.01 mGy.
