摘    要:Luminescence spectra of SrAl12O19:Pr^3+,Mn^2+ under VUV-UV excitation are investigated. The characteristic emissions between 4f levels and the excitation of 5d for Pr^3+ are observed. The emission of Mn^3+ peaks at 517nm and the excitations clue to the ground to multiplets are observed at 276, 360, 386 and 426nm. However, the spectral overlap between the emission of Pr^3+ and excitation of Mn^2+ is absent, suggesting that the quantum splitting cannot be achieved via a Pr^3+ Mn^2+ ion pair in the host SrAl12O19.
