Near Infrared Emission

The visible and near infrared emission spectra of Er3+/Tm3+-doped Ga2O3-Bi2O3-PbO-GeO2(GBPG) glasses excited at 808 nm are experimentally investigated. The results reveal that 1.53 µm emission were enhanced with an increase of Er3+concentration. Furthermore, the incorporation of Er3+into Tm3+-doped systems has also resulted in intense 522, 545 and 693nm upconversion emission intensity and an weak 660 nm red emission. The possible mechanism and related discussions on this phenomenon have been presented. The results show that Er3+/Tm3+-codoped GBPG glass may be a promising materials for developing laser and fiber optical devices.

Cr3+/Ni2+ co-doped optically transparent magnesium aluminosilicate glass-ceramics containing MgAl2O4 nanocrystals have been prepared by heat-treatment. Greatly enhanced broadband near-infrared emission centered at 1216 nm in Cr3+/Ni2+ co-doped glass ceramics is observed when compared with the Ni2+ single-doped glass ceramics under 532 nm excitation. The observed enhancement of infrared emission is attributed to the energy transfer from Cr3+ to Ni2+ ions in the nanocrystalline phase, which leads to the emission due to 3T2(3F) → 3A2(3F) transition of octahedral Ni2+ ions.
