A strategy is proposed to fabricate dual-mode luminescent NaGdF4 nanocrystals that are composed of NaGdF4:Yb3+,Tm3+ core and NaGdF4:Eu3+ shell. Intense downconversion via the sensitization Gd3+ upconversion luminescence Eu3+ one order magnitude higher than triply-doped only counterparts have been achieved by employing distinct core/shell nanostructures double sensitizations Yb3+ Tm3+.
