| Abstract: | The phosphors in the system Y3−xAl5-yO12:xCe3+,yCr3+ were synthesized by solid-state reactions and their photoluminescence properties were investigated. These phosphors have absorption in the visible light region and give luminescence in the far-red region (∼688 nm), which are suitable for the application in the device of luminescent solar concentrator (LSC). In these phosphors, Ce3+ located at Y3+ site can effectively transfer its absorbed energy to Cr3+ at Al3+ site. |
