N2 - 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 Er 3+. Evaluation of its optical properties using the 157-nm emission of a F2 laser reveal that it has a 163-nm vacuum ultraviolet fluorescence with 1.3-μs decay time, involving a transition originating from the high-spin state of the 4f 105d excited state configuration. This is one of the shortest emission wavelengths from solid-state materials reported at room temperature.
