| 中文摘要 | we report on the conversion of near-ultraviolet radiation of 250-350 nm into near-infrared emission of 970-1100 nm in yb3+-doped transparent glass ceramics containing ba2tisi2o8 nanocrystals due to the energy transfer from the silicon-oxygen-related defects to yb3+ ions. efficient yb3+ emission (f-2(5/2)-> f-2(7/2)) was detected under the excitation of defects absorption at 314 nm. the occurrence of energy transfer is proven by both steady state and time-resolved emission spectra, respectively, at 15 k. the yb2o3 concentration dependent energy transfer efficiency has also been evaluated, and the maximum value is 65% for 8 mol % yb2o3 doped glass ceramic. these materials are promising for the enhancement of photovoltaic conversion efficiency of silicon solar cells via spectra modification. |
