| 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.
