Abstract:
We have prepared Tl-doped NH 4 Br translucent ceramics by spark-plasma sintering and evaluated their photoluminescence (PL) and photostimulated luminescence (PSL) properties. In PL, two luminescence peaks appeared due to 3 P 1 → 1 S 0 transitions of Tl + and off-center self-trapped excitons (STEs) localized around Tl + in all the samples. In PSL, the 0.1%–3% Tl-doped samples showed luminescence related to the off-center STEs around 500 nm by stimulation light at 630 nm. When correlations between exposure dose and PSL intensity were examined, we confirmed that the 0.1%–1% and 3% Tl-doped samples showed linear responses over ranges of 10–10 000 and 1–10 000 mGy, respectively.
