A strategy is proposed to fabricate dual‐mode luminescent NaGdF 4 nanocrystals that are composed of NaGdF 4 :Yb 3+ ,Tm 3+ core and NaGdF 4 :Eu 3+ shell. Intense downconversion via the sensitization of Gd 3+ and upconversion luminescence of Eu 3+ that is one order of magnitude higher than the triply‐doped core only counterparts have been achieved by employing the distinct core/shell nanostructures and double sensitizations of Yb 3+ and Tm 3+ .
