摘要：
Single crystal of ErAl3(BO3) (4) was grown and its structure was studied. Polarized absorption spectra of ErAl3(BO3)(4) single crystal were measured in the spectral range 1670-330 nm (6000-30000 cm (1)). The Judd-Ofelt spectroscopic parameters have been determined: Omega(2) = 4.87 x 10 (20) cm(2), Omega(4) = 2.49 x 10 (20) cm(2), Omega(6) = 2.72 x 10 (20) cm(2). These parameters have been used to calculate the radiative transition probabilities, the multiplet luminescence branching ratios and the fluorescence life times of the manifolds. The luminescence spectra due to transitions H-2(11/2) -> I-4(15/2) (526 nm), S-4(3/2) -> I-4(15/2) (548 nm), F-4(9/2) -> I-4(15/2) (662 nm), H-2(11/2) -> I-4(13/2) + I-4(9/2) -> I-4(15/2) (800 nm) and S-4(3/2) -> I-4(13/2) (855 nm) were recorded in a, r and p polarizations. The most intensive luminescence belonged to S-4(3/2) -> I-4(15/2) transition (548 nm). (C) 2013 Elsevier B.V. All rights reserved.
