Abstract

We have investigated the photoluminescence (PL), scintillation, and photostimulated-luminescence (PSL) properties of Yb-doped SrCl2 transparent ceramics. The samples were prepared using the spark plasma sintering method. Emission peaks in the PL, scintillation, and PSL spectra were observed at 380 and 405 nm due to the spin-allowed and spin-forbidden 4f135d1–4f14 transitions of Yb2+, respectively. The PL quantum yield (QY) value elevated with increasing Yb concentration at 0.05%–1.0%, and the 1.0% Yb-doped SrCl2 transparent ceramic indicated the highest QY value. This concentration dependence was similar for the scintillation and PSL intensities.

掺镱 SrCl2 透明陶瓷的闪烁和光刺激发光特性

我们研究了掺镱 SrCl2 透明陶瓷的光致发光 (PL)、闪烁和光刺激发光 (PSL) 特性。样品采用火花等离子烧结法制备。由于 Yb2+ 的自旋允许跃迁和自旋禁止跃迁 4f135d1-4f14 的缘故，在 380 和 405 纳米波长处观察到了聚光、闪烁和 PSL 光谱中的发射峰。随着掺镱浓度（0.05%-1.0%）的增加，聚合量子产率（QY）值也随之升高，掺镱浓度为 1.0% 的 SrCl2 透明陶瓷的 QY 值最高。这种浓度依赖性与闪烁强度和 PSL 强度相似。
