摘要：

An investigation of Ce-activated borate-rich borosilicate glasses was performed in a composition range previously unexplored, with high B2O3:SiO2 ratios from 4.83:1 to 8.75:1. Glass samples were prepared by the melt quenching method in air. Samples were individually heated for 15 min at 1000 degrees C, evaluated for weight loss due to the release of volatile species, followed by a final melt for 15 min at 1000 degrees C, and then annealed at 350 degrees C for one hour to enhance stability. Particular emphasis was placed on the luminescence of the glasses investigated under X-ray and ultraviolet excitation. Luminescence was interpreted in terms of defects and Ce3+ in different environments. The results indicated it was possible to achieve a composition of the host matrix that exhibited ultraviolet transparency cutoff at 326 nm and a well-defined emission from Ce3+, especially under X-ray excitation.
