Аннотация: Single crystals of the ErFe3(BO3)(4) borate were synthesized and their structure was studied. Absorption spectra of the Er3+ ion in sigma- and pi-polarizations of f-f transitions (4) I (15/2) -> (4) I (13/2), (4) I (11/2), (4) I (9/2), (4) F (9/2), (4) S (3/2), (2) H (11/2), and (4) F (7/2) were measured. The refractive index and bПоказать полностьюirefringence were measured as a function of the wavelength. The transition intensities were analyzed within the Judd-Ofelt theory, and the following parameters of the theory were obtained: Omega(2) = 7.056 x 10(-20) cm(2), Omega(4) = 1.886 x 10(-20) cm(2), and Omega(6) = 2.238 x 10(-20) cm(2). Using these parameters, the radiative transition probabilities, luminescence branching ratios, and radiative lifetimes of multiplets were calculated.
