The Laser induced fluorescence spectra and excitation decay process of Ni2+ doped with chrysoberyl were studied in temperature rang of 10 K to 300 K. It was shown that the intrinsic radiative lifetime of 3T2g state is 123±7.2 μs. Mott activation energy is 1147 cm-1. Ni2+:BeAl2O4 Crystal has considerable high radiative rate and luminescence efficiency at room temperature and is a possible good candidate for making tunable laser.
