Luminescence of transparent glass ceramics containing Er3+ and Yb3+ zirconate-titanate nanocrystals

Luminescence regularities have been studied in new erbium/ytterbium materials based on glasses and glass ceramics of a magnesium-aluminosilicate system containing nanoscale erbium/ytterbium zirconate titanate crystals with the pyrochlore structure. Lifetimes of Yb 3+ and Er 3+ ions in the 2  F 5/2 s...

Description
Summary:Luminescence regularities have been studied in new erbium/ytterbium materials based on glasses and glass ceramics of a magnesium-aluminosilicate system containing nanoscale erbium/ytterbium zirconate titanate crystals with the pyrochlore structure. Lifetimes of Yb 3+ and Er 3+ ions in the 2  F 5/2 state and in the 4 I 11/2 and 4 I 13/2 states, respectively, and the efficiency of Yb 3+  → Er 3+ energy transfer have been evaluated. The identified spectral-luminescent characteristics of the studied glasses and glass ceramics co-doped with erbium and ytterbium ions show that these materials are promising media for producing laser generation in the spectral range around 1.5 μm.
