Optical Characterization of Phosphate Glass with Additional Aluminum/Tin Impurities

Abstract

The optical properties of phosphate glass (PG) with two different impurities, namely, aluminum and tin, were investigated. Broad white luminescence was observed from PGs with tin and aluminum impurities under deep ultraviolet exposure. Through emission and excitation spectroscopy and decay curve measurement, it is assumed that the origin of the broadband luminescence differs depending on the impurities introduced. In addition, time-resolved emission spectral analysis revealed the difference in decay constant at each wavelength. The results obtained in this study might give important information about two potential impurities of PG for a better understanding of background noise and the functions of widely used radiophotoluminescence (RPL) dosimeters.

Radiation-induced Luminescence Properties of Ce-doped ZnBr2-based Glasses

“…(27,28) Therefore, the development of glass scintillators for X-and γ-ray detectors is expected. The scintillation properties of various oxide glass scintillators such as borate, (29)(30)(31)(32) silicate, (33)(34)(35)(36)(37)(38) phosphate, (39)(40)(41)(42)(43)(44) and tellurite glasses (45)(46)(47) have been reported. In recent years, Ce-doped oxyhalide and halide glasses have attracted much attention because of advantages including a low synthesis temperature and a low phonon energy compared with oxide glasses.…”

Development of micrometer-scaled aluminum-enriched phosphate glass beads with a silver activator for real-time profile measurement of a clinical carbon beam

“…In this study, we investigated an alternative partner for the silver activator that has better responses in real-time radioluminescence. Based on our previous observation of strong, broadband visible light emission from aluminum-enriched phosphate glass only under deep ultraviolet exposure, 27) we hypothesized that aluminum-enriched phosphate glass may emit strong radioluminescence under radiation exposure. This type of glass also has limited luminescent emissions under 365 nm ultraviolet irradiation.…”
