摘要：

The observation of photon-cascade emission (PCE) in Pr3+ activated SrAl12O19 under vacuum ultraviolet excitation (VUV) is reported and discussed, In this host lattice, the lowest-energy component of the Pr3+ 4f5d excited configuration is located above the S-1(0) state. The excitation of the Pr3+ 4f5d state by WV photons results in radiative emission originating from the S-1(0) level stare. The subsequent radiative emission from the P-3(0) State confirms the photon-cascade emission of Pr3+ activated SrAl12O19. To the best of our knowledge this is the first observation of PCE in an oxide matrix.
