Effect of Network-Forming Oxides on Long-Lasting Phosphorescencein Mn2+ Doped ZnO-B2O3-SiO2 Glass
Mn2+-doped zinc borosilicate glasses (ZSBM) with excellent long-lasting phosphore- scence (RTSLLP) and photostimulated long-lasting phosphorescence (PSLLP) were successfully synthesissed by high tempreture solid-state reaction. Through increasing the ratio of SiO2/ B2O3 with fixing the content of ZnO in 60mol%, RTSLLP and PSLLP were improved obviously. By TL study, it was seen that the traps concentration had a big change with the increasing in silica content, which bringed a positive impact on the RTSLLP and PSLLP, especially PSLLP performance, and through infrared absorption spectrum analysis, it was confirmed that the distribution of trap-level was closely related to the silicon oxygen groups and boron oxygen groups.
