△ [5p-C14-14] Development of Cr/Nd/Yb:YAG ceramic suitable for broadband visible light excitation
Keywords:YAG, ceramic, Yb
Cr and Nd co-doped Yb:YAG ceramics absorb broadband visible solar light or flash lamp enhancing Yb 1030-nm fluorescence. This characteristic is suitable for near infrared laser materials and is promising for improving conversion efficiency of the solar cell. In this study, we measured fluorescence properties of the ceramic powders made by sol-gel method and analyzed the effect of doping densities on the energy transfer from Cr and Nd to Yb.
