Abstract

Optical absorption and emission intensities have been investigated for the Nd3+ ion in α-Ba3Y(BO3)3 crystal. Based on the Judd-Ofelt theory the spectral parameters were obtained. The intensity parameters Ωλ are: Ω2 = 0.62 × 10−20 cm2, = 0.90 × 10−20 cm2, Ω6 = 1.06 × 10−20 cm2. The radiative lifetime is 1104 μs, and quantum efficiency is equal to 6.9%. The fluorescence branching ratios are: β1 (0.88 μm) = 0.4050, β2 (1.06 μm) = 0.4897, β3 (1.35 μm) = 0.1000 and β4 (1.88 μm) = 0.0053.
