英文摘要	Eu2+ or Cr3+ singly doped and Eu2+-Cr3+ co-doped MgSrAl10O17 luminescent materials were synthesized by solid-state reactions and their photoluminescence properties were investigated. These luminescent materials have absorption in the UV-Vis region and give luminescence in the deep-red region (similar to 693 nm), which are suitably applied in a device of luminescent solar concentrator (LSC) for improving the efficiency of silicon solar cells. In these luminescent materials, Eu2+ located at Sr2+ site can effectively transfer its absorbed energy to Cr3+ at Al3+ site. The energy transfer from Eu2+ to Cr3+ takes the dipole-dipole interaction mechanism. The transfer efficiency (eta(ET)) approaches about 0.63 and the optimized quantum efficiency (QE) for Cr3+ emission is about 11%. (C) 2011 The Electrochemical Society.
