Abstract The structure, ultraviolet (UV) transparency, luminescence, and scintillation of CeO2-doped (0.1 mol%) borosilicate glasses containing Sb2O3, SnO2 or P2O5 were investigated. Glasses were prepared by melt quenching in air and characterized by several spectroscopy techniques: Raman scattering, optical absorption, photoluminescence (PL), fluorescence lifetime, thermoluminescence, and radioluminescence. Raman scattering results presented three major groups of vibrational modes, within 230–850 cm−1, 850-1250 cm−1, and 1250-1600 cm−1. Luminescence was dominated by a broad band centered at around 360–380 nm, depending on the chemical composition of the glass. Photoluminescence presented a dominant (96–98%) fast decay time of 36–40 ns that was ascribed to Ce3+. The P2O5-containing glass showed the highest scintillation output under X-ray excitation.

Ce掺杂硼硅酸盐玻璃的闪烁、发光和光学特性

摘要 研究了含有 Sb2O3、SnO2 或 P2O5 的 CeO2 掺杂 (0.1 mol%) 硼硅玻璃的结构、紫外 (UV) 透明度、发光和闪烁。玻璃是通过在空气中熔融淬火制备的，并通过几种光谱技术表征：拉曼散射、光吸收、光致发光 (PL)、荧光寿命、热致发光和辐射发光。拉曼散射结果显示了三组主要的振动模式，在 230-850 cm-1、850-1250 cm-1 和 1250-1600 cm-1 内。发光主要由集中在 360-380 nm 附近的宽带主导，具体取决于玻璃的化学成分。光致发光表现出 36-40 ns 的主要 (96-98%) 快速衰减时间，这归因于 Ce3+。
