Abstract:

Bi ions-doped materials have attracted increasing attention because of their potential applications in LED light sources and imaging displays. However, the correlation between local glass network structure and visible emission of Bi ions is rarely discussed, which hinders the optimization of Bi ions-doped glass. In this work, we prepared the Bi ions-doped borosilicate glasses (Bi-Glass) with tunable visible emissions by changing the content of B2O3. Their optical properties, structure, and temperature-dependent emission were investigated systematically. All the Bi ions-doped glasses show broadband luminescence from 350 nm to 700 nm, the emission bands show a blue shift from 454 nm to 435 nm when the concentration of B2O3 increases from 0% to 10%. The emission intensity reaches the maximum value of 5% B2O3 concentration, which attributes to the number and distribution of bismuth ions luminescent centers. Furthermore, thermoluminescence is observed in this glass system. In this study, the coordination structure around the active centers of bismuth can be changed by modifying the glass network structure, promoting the research of tunable luminescence of bismuth ions-doped glass.
