Реферат: | eng: Optical absorption and luminescence spectra of ytterbium and terbium codoped BaB 2O 4 (β-BBO and α-BBO) crystals grown in different conditions have been studied. Low-temperature absorption peaks were observed in all samples. Features related to rare earth ions were observed in absorption and luminescence spectra. Absorption and emission in the range 860-1000 nm are caused by 2F 5/2↔ 2F 7/2 transitions in Yb 3 ions. Emission peaks at 500, 550, 590 and 630 nm correspond to 5D 4→ 7F 6, 7F 5, 7F 4, and 7F 3 transitions of Tb 3 ions, respectively. The probable reasons of variations in spectroscopic features related to Yb in BBO host are discussed. It has been shown that the replacement of 2 by Yb 3 in the lattice of 24 results in the decrease in the symmetry of oxygen surrounding of Yb 3. © 2012 Elsevier B.V. All rights reserved.
