Near-Infrared Photocatalytic Upconversion Nanoparticles/TiO2 Nanofibers Assembled in Large Scale by Electrospinning

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 und...

Zusammenfassung: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.
