WebIn order to enhance visible light photo-activity, CuO nanoparticles were coupled with NaYF4:(Yb,Er) by mechanical ball-milling and coated with TiO2-sol. The coupling of CuO nanoparticles with NaYF4:(Yb,Er)/TiO2 caused the formation of a NaYF4:(Yb,Er)-CuO/TiO2 composite capable of visible absorption with a remarkably reduced band gap of ~2.5 eV. WebThe hot‐injection synthesis of manganese ion (Mn 2+ )‐doped NaYF 4 :Yb,Er nanocrystals (NCs) with red up‐converting emission and the diameter tunable from 8 to 15 nm is demonstrated. The Mn 2+ dosage, growth temperature, and heating rate determine the doping modes, including surface doping and interior doping.
