摘要：

We report the successful growth of trivalent erbium-doped lithium calcium aluminum fluoride (Er3+:LiCaAlF6) using the micro-pulling down method. Several absorption bands were observed at 139 nm (71,942 cm(-1)), 149 nm (67,114 cm(-1)), and 162 nm (61,728 cm(-1)), which can be ascribed to 4f -> 5d transitions in Er3+ Evaluation of its optical properties using the 157-nm emission of a F-2 laser reveal that it has a 163-nm vacuum ultraviolet fluorescence with 1.3-mu s decay time, involving a transition originating from the high-spin state of the 4f (10)5d excited state configuration. This is one of the shortest emission wavelengths from solid-state materials reported at room temperature. (C) 2011 Elsevier B.V. All rights reserved.
