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.

In this article, we report on enhanced broadband near-infrared emission in Yb–Bi codoped phosphate glasses. The emission intensity of Yb–Bi codoped glass was ˜32 times larger than that of Bi-doped glass when excited with 980-nm laser diode. The highest 1/e fluorescent lifetime of Yb–Bi codoped glass reached 1650 μs. The dependence of emission intensity and fluorescent lifetime on Yb2O3 concentration was investigated. The enhancement of the near-infrared emission is due to energy transfer from Yb3+ (2F5/2–2F7/2) transition to Bi ions, and the highest energy transfer efficiency reached 50%. Yb–Bi codoped phosphate glass should be a promising candidate for broadband optical amplification.

Transparent glass ceramics containing Li2MgSiO4: Cr4+ nanocrystallites were prepared. Intense broadband near-infrared emission with full width at half-maximum larger than 200 nm and long fluorescence lifetime (τ > 100 μs) were observed. The temperature-dependent optical characteristics of the glass ceramics containing Li2MgSiO4: Cr4+ crystallites were compared to those of Li2MgSiO4: Cr4+ single crystals. The reason for extra-long near-infrared fluorescence lifetime was illuminated by the mixed effect between 3T2 and 1E levels. The crystal-filed-induced particular energy-level scheme makes the fluorescence lifetime of the glass ceramics containing Li2MgSiO4: Cr4+ crystallites one order longer than those of other Cr4+-doped glass ceramics.
