| Abstract | Upconversion properties of the glass with the composition 70GeO2+ (29.5-x) PbF2+ 0.5 Er2O3 + x Yb2O3 glasses, where x= 0, 0.5 and 1.5 mol. % under 808 nm excitation was investigated. The intense green (534 and 550 nm) and red (639 nm) emissions corresponding to the transitions H11/2 →I15/2, S3/2 → I15/2 and F9/2 → I15/2, respectively, were simultaneously observed at room temperature. The PbF2 content offered an important influence on upconversion luminescence emission effectiveness. With increasing PbF2 content, the intensities of the green (534 nm) and red (639 nm) emissions increase slightly, while the green (550 nm) emission increases significantly. The results were explained on the basis of electron-phonon interaction. |
