Abstract
Abstract 30BaO–(70-x)TiO2–xGeO2 (x = 50, 55, 60; BTG) glass and glass-ceramics samples were prepared by a melt-quenching method, and the optical and X-ray induced scintillation properties were investigated. In this study, we prepared twelve different samples: three different compositions (BTGx; x = 50, 55 and 60), two different melting temperatures (1250 and 1550 °C), and with/without crystallization process. The crystallization phenomenon was confirmed by XRD analysis. In photoluminescence spectra, only one broad emission peak at 520 nm was observed in the glass samples, while another peak was observed in glass-ceramic samples at 450 nm in addition to 520 nm peak. The similar tendency was also observed in X-ray induced scintillation spectra. According to the crystallization, the scintillation efficiency was enhanced.
