TiO2 composite nanotubes embedded with CdS and upconversion nanoparticles for near infrared light driven photocatalysis

TiO2 nanotubes embedded with a high proportion of NaYF4:Yb/Tm@NaYF4:Yb/Er upconversion nanoparticles and CdS nanoparticles are prepared using a colloidal solution method and electrospinning, and show excellent fluorescence energy transfer efficiency and photocatalytic performance.
