Abstract

The polarized absorption spectra of trigonal single crystal Nd _0.5Gd _0.5Fe ₃(BO ₃) ₄ were measured in the spectral range 10,000-22,000 cm ^-1. The d-d and f-f transitions spectra were separated. The f-f transitions intensities were analyzed in terms of the Judd-Ofelt theory in a ferroborate with huntite structure for the first time, and the following parameters of the theory were obtained: Ω ₂ = 4.4 × 10 ^-20 cm ², Ω ₄ = 8.04 × 10 ^-20 cm ², and Ω ₆ = 8.25 × 10 ^-20 cm ². The strengths, spontaneous emission probabilities, branching ratios, spectroscopic quality factor and excited state lifetime were calculated for transitions from the ⁴F _3/2 state to ⁴I _J manifold. All the obtained spectroscopic characteristics were compared with those of alumoborates with the same crystal structure.
