摘要：
The luminescence properties of green emitting strontium aluminate phosphor SrAl12O19 doped and co-doped with Mn2+ and Tb3+ were studied using synchrotron radiation. It is shown that Tb3+, exhibiting a strong absorption band in the vacuum-ultraviolet (VUV), provides sensitisation of Mn2+ emission in this host. The observed sensitisation effect of the Tb-Mn pair can be used for improving the efficiency of VUV phosphors. (c) 2009 Elsevier B.V. All rights reserved.
