Ce^3+/Er^3+/Bi^3+ triply-doped yttrium aluminum garnet (YAG) is synthesized using co-precipitation method. The Bi^3+ concentration-dependent near-infrared (NIR) emission behavior is systemically in- vestigated. The NIR emission of Er^3+ ions at 1531 nm is enhanced threefold by the addition of 7 mol% Bi^3+. Bi^3+doping results in the formation of exciton in YAG and the variation in the local environment of the doped rare-earth ions. The enhancement in NIR luminescence is ascribed to the combined effects of the sensitization of exciton→Ce^3+ →Er^3+ and the Bi^3+ doping-induced adjustment of the local environment for Ce^3+ and Er^3+ ions. 相似文献
