Radio-photoluminescence Properties of Sm-doped HfO2–Al2O3–SiO2 Glass Ceramics

In this study, Sm-doped HfO 2 -Al 2 O 3 -SiO 2 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 Sm 3+ , and the 1.0% Sm-doped sample showed the luminescence of Sm 2+ and Sm 3+ .Alternatively, the 3.0% Sm-doped sample mainly showed the luminescence of Sm 2+ .The radio-photoluminescence phenomenon (Sm 3+ Sm 2+ ) 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.
