研究了20 SrO-20 BaO-40 Nb 2 O 5 - 20 P2 O 5（SBNP）玻璃和含Sr0.5Ba0.5Nb2O6微晶的微晶玻璃的闪烁和热释光性能。SBNP玻璃是通过传统的熔融淬火方法制备的。将所得玻璃在不同温度和保温时间下退火，以用于纳米微晶的成核和生长。X射线衍射分析表明，样品为玻璃或微晶玻璃，且在较高的温度和较长的保温时间下进行热处理，有利于晶化。此外，玻璃陶瓷的辐射发光和TL强度高于玻璃，因此，在玻璃陶瓷中可以产生有效的发光。
We have investigated scintillation and thermoluminescence properties of the 20SrO-20BaO-40Nb2O5-20P2O5(SBNP) glass and glass-ceramics containing Sr0.5Ba0.5Nb2O6crystallites. The SBNP glasses were prepared by a conventional melt-quenching method. The obtained glasses were annealed at various temperatures and holding times for nucleation and growth of nanocrystallites. X-ray diffraction patterns revealed that samples were either glass or glass-ceramic containing Sr0.5Ba0.5Nb2O6nanocrystallites, and heat treatments at higher temperatures and longer holding times have promoted the crystallization. Furthermore, radioluminescence and TL intensities were higher for the glass-ceramics than glass; thus, efficient luminescence can be yielded in glass-ceramics.
