Luminescence and scintillation of high silica glass containing SnO

Abstract High silica glasses containing SnO were prepared by sintering solution-doped porous silica glasses. The sample sintered in the CO reducing atmosphere exhibited a strong emission at 400 nm under 269 nm excitation with a lifetime of 11 μs, and its intensity was much stronger compared to that of the sample sintered in the air atmosphere. Under X-ray excitation, broad radioluminescence ranging from 300 to 600 nm was observed and the maximum integral intensity was 122% of Bi 4 Ge 3 O 12 (BGO).
