Abstract
A shell of SiO<sub>2</sub> with tunable thickness was uniformly coated on NaGd(WO<sub>4</sub>)<sub>2</sub>:Yb<sup>3+</sup>/Er<sup>3+</sup> core upconversion nanoparticles (UCNPs). The effects of the silica shell on UC luminescence and thermal sensing properties of the core–shell UCNPs were investigated.
