Description:
Scintillators, which convert high-energy ray into visible light, have become a research hotspot because they are extensively applied in security inspection, medical diagnostics and scientific research. However, traditional scintillation crystals suffer from the complex preparation process, high cost and difficulty in mass production, inhibiting the practical applications. Here, Tb3+ doped sodium silicate glass that avoids above shortcomings was successfully synthesized, which exhibits prominent scintillation property. The X-ray excited integral intensity of the representative glass can reach up to 149.9% of that of Bi4Ge3O18. The damaged glass induced by X-ray can be restored easily after heat treatment again, confirming the excellent reusability. Moreover, the sample reveals outstanding luminescence performance with the internal quantum efficiency up to 97.8% and wonderful thermal stability. The fluorescence intensity at 573 K still maintains 96% of that at room temperature. These results verify that the obtained glass as a scintillator possesses potential application prospects
