文摘

Large-scale fabrication of upconversion nanoparticles (UCNPs)/TiO₂ nanofiber mats is achieved via electrospinning, followed by calcination. The as-prepared UCNPs/TiO₂ nanofiber mats consist of nanofibers of TiO₂ embedded with UCNPs of NaYF₄:Yb/Tm@NaYF₄, confering strong upconversion fluorescence under near-infrared excitation (980 nm) and enabling efficient degradation of organic dyes via fluorescence resonance energy transfer between UCNPs and TiO₂.
