Аннотация: The Judd–Ofelt theory has been applied to analyze absorption spectra of Ho3+ ion in HoAl3(BO3)4 measured in spectral range 300–700 nm at room temperature. The Judd–Ofelt spectroscopic parameters have been determined as: Ω2 = 18.87 x 10 -20 cm2, Ω4 = 17.04 x 10 -20 cm2, Ω6 = 9.21 x 10 -20 cm2. These parameters have been used to calculate radiative lifetimes and branching ratios of the luminescence manifolds. Three luminescent bands were found in the spectral range 450–700 nm ascribed to transitions from the 5F5, (5F4, 5S2) and 3K8 states to the ground state 5I8. Experimental intensities of these luminescence transitions were compared with those calculated by using Judd–Ofelt theory and the system of kinetic equations for populations of starting luminescing states. Probabilities of radiativeless transitions were evaluated from this comparison.

Аннотация: High-optical-quality single crystals of the TmAl3(BO3)(4) compound were synthesized from a solution in the melt. The absorption spectra in the sigma and pi polarizations for the H-3(6) - F-3(4), H-3(6) - H-3(5), H-3(6) - H-3(4), H-3(6) - F-3(3), H-3(6) - F-3(2), H-3(6) - (1)G(4), and H-3(6) - D-1(2) transitions in the Tm3+ ion were recorded at room temperature. The transition intensities were analyzed in the framework of the Judd-Ofelt theory generalized to the case of anisotropic crystals, and the following parameters of the theory were obtained: Omega(2) = 6.14 x 10(-20) cm(2), Omega(4) = 3.09 x 10(-20) cm(2), and Omega(6) = 2.04 x 10(-20) cm(2). The lifetimes and the branching ratios were determined for all possible transitions.
