Large‐scale fabrication of upconversion nanoparticles (UCNPs)/TiO 2 nanofiber mats is achieved via electrospinning, followed by calcination. The as‐prepared UCNPs/TiO 2 nanofiber mats consist of nanofibers of TiO 2 embedded with UCNPs of NaYF 4 :Yb/Tm@NaYF 4 , 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 TiO 2 .
