In this study, Sm-doped HfO2-Al2O3-SiO2 glass ceramics with different Sm concentrations (0.1, 0.3, 1.0, and 3.0%) were synthesized by the melt quenching method using a floating zone (FZ) furnace. Their photoluminescence properties, including radio-photoluminescence and spatial resolution, were investigated. The 0.1 and 0.3% Sm-doped samples indicated the luminescence of Sm3+, and the 1.0% Sm-doped sample showed the luminescence of Sm2+ and Sm3+. Alternatively, the 3.0% Sm-doped sample mainly showed the luminescence of Sm2+. The radio-photoluminescence phenomenon (Sm3+ → Sm2+) was observed in the 0.1-1.0% Sm-doped samples. In addition, the 1.0% Sm-doped sample had a spatial resolution of 10 LP/mm. [ABSTRACT FROM AUTHOR] |
