Spectroscopic analysis of Nd:BGSO crystal grown by the micro-pulling-down method

Up-conversion luminescence and Judd–Ofelt analysis of Nd2O3-doped yttria stabilized zirconia single crystals

“…12 for (ZrO 2 ) 92 (Y 2 O 3 ) 8-x (Nd 2 O 3 ) x single crystals with different Nd 2 O 3 contents. These all show the three emission bands corresponding to the Nd 3+ 4 F 3/2 → 4 I 9/2 (894/957 nm), 4 F 3/2 → 4 I 11/2 (1064/1128 nm), and 4 F 3/2 → 4 I 13/2 (1332 nm) transitions that are characteristic of Nd 3+ doped materials, [43][44][45] but the narrow linewidths in these single crystal samples allow each of the first two bands to be resolved into two components, which are related to distortions in the local environment for Nd 3+ in (ZrO 2 ) 92 (Y 2 O 3 ) 8−x (Nd 2 O 3 ) x single crystals. Of these, the main emission maximum occurs at 1064 nm, and can be used for lasers with an emission wavelength of around 1.06 μm.…”
