Spectral parameters of Nd3+ ion in Sr6NdSc(BO3)6 crystal

Abstract

The spectroscopic study of Nd3+ in Sr6NdSc(BO3)6 crystal had been performed. Based on the Judd-Ofelt theory to analyze the optical strengths measured in absorption spectra, the following spectral parameters were obtained: intensity parameters Ωlambda; are Ω2 = 1.108 × 10−20 cm2, Ω4 = 2.884 × 10−20 cm2, Ω6 = 3.085 × 10−20 cm2, the radiative lifetime is 385 μs, the quantum efficiency is 12.5%. The fluorescence branch ratios were calculated: β1 = 0.423, β2 = 0.482, β3 = 0.092, β4 = 0.005.
