This paper reports the growth and optical properties of Cr3+-doped LaSc3(BO3)(4) (Cr3+ :LSB). The Cr3+ -doped LaSc3(BO3)(4) crystal with dimension null set 25 x 35 mm(3) was obtained by Czochralski method. The absorption and photoluminescence spectra have been measured. The dominant features of absorption spectrum are two broadbands at ca. 400-700 nm. A broad emission band extending from 740 to 1280 nm with a peak at near 960 nm was observed. The lifetime of Cr3+ :LSB was 15 mus. (C) 2002 Elsevier Science B.V. All rights reserved.
