The upper limit of Tm<sup>3+</sup> doping concentration increases from the well accepted 0.5% to 3% in NaGdF<sub>4</sub>@Yb/Tm:NaGdF<sub>4</sub> NCs with an inert-core/active-shell structure, and the UC intensity increases about 6 times, benefiting from the enhanced energy transfer efficiency from the Yb<sup>3+</sup> to Tm<sup>3+</sup> ions by confining them in a two-dimensional space.
