Growth and spectroscopic studies of Nd3+-doped BaBi2(MoO4)4 crystal

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, 43–45 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.…”

Polarized spectral properties and laser operation of Nd:SrAl12O19 crystal

“…The spontaneous transition rate, branching ratios and the radiative lifetime of 4 F 3/2 → 4 I 9/2 , 4 F 3/2 → 4 I 11/2 , 4 F 3/2 → 4 I 13/2 and 4 F 3/2 → 4 I 15/2 transitions of Nd:SRA crystal are given in Table 2. We can see that the branching ratio of the 4 F 3/2 → 4 I 9/2 transition is smaller than that of the 4 F 3/2 → 4 I 11/2 transition for σ polarization, but larger than that of the 4 (500 μs at 792 nm [16]), Nd:KGd(WO 4 ) 2 (111 μs [22]), Nd:Bi 4 Ge 3 O 12 (293 µs [23]), and Nd:BaBi 2 (MoO 4 ) 4 (115 µs [24]). The results indicate that Nd:SRA crystal has a higher energy storge ability.…”
