Abstract :
LiCaAlF6:Cr3+ (Cr3+:LiCAF) exhibits an intrinsic (extrapolated maximum) slope efficiency of 67%. For comparison, the intrinsic slope efficiencies of BeAl2O 4:Cr3+ (alexandrite), Na3Ga2Li3F12:Cr3+ and ScBO3:Cr3+ were found to be 65, 28, and 26%, respectively. The tuning range of LiCaAlF6:Cr3+ was determined to be at least 720-840 nm. The conventional spectroscopic properties, such as the absorption, emission, and emission lifetimes as a function of temperature, are reported as well
