Abstract The emission spectra of SrAl12O19∶Pr3+ at temperature from 308 to 483 K were investigated under vacuum ultraviolet excitation. Both the dipole-forbidden 4f2→4f2 transition and the dipole-allowed 4f5d→4f2 transitions were observed. The intensity of the 4f5d→4f2 emission relative to that of the 4f2→4f2 emission increased with increasing temperature. A thermal equilibrium model was applied to the system consisting of the 1S0 state and the lowest 4f5d states of Pr3+, and the temperature dependence of emission spectra of Pr3+ in the Pr3+-doped SrAl12O19 was well explained.
