文摘

•: Core-shell NaYF₄:Yb,Tm@SiO₂@TiO₂ NPs were synthesized via a sequential coating method.
•: Hybrid NaYF₄:Yb,Tm@SiO₂@TiO₂ NPs show NIR-light enhanced photocatalytic activity.
•: NIR-driven antibacterial performance has been realized with NaYF₄:Yb,Tm@SiO₂@TiO₂ NPs.
•: Working mechanism of the hybrid photocatalysts as antibacterial agents was proposed.
