title: Synthesis of lanthanide-doped NaYF₄@TiO₂ core-shell composites with highly crystalline and tunable TiO₂ shells under mild conditions and their upconversion-based photocatalysis.
abstract: NaYF4:Yb,Tm@TiO₂ core-shell composites were synthesized via a facile hydrothermal method. The highly crystalline TiO₂ shell can be uniformly coated onto lanthanide-doped NaYF₄ microrods and nanorods under mild conditions without calcination. The thickness of the TiO₂ shell can be tuned by varying the ratio of fluoride rods and Ti precursors. The microcomposite with a moderate TiO₂ shell shows excellent photocatalytic activity under near-infrared irradiation.
