Monodisperse Silica‐Coated Polyvinylpyrrolidone/NaYF4 Nanocrystals with Multicolor Upconversion Fluorescence Emission

Year: 2006

Type: article

Abstract: In full color: Ultrafine lanthanide-doped polyvinylpyrrolidone/NaYF4 nanocrystals with narrow size distribution were synthesized and found to disperse well in water and many organic solvents. Silica was coated onto the nanocrystals to form a uniform thin layer. Highly efficient upconversion fluorescence was observed from both uncoated and silica-coated PVP/NaYF4 nanocrystals doped with Yb/Er or Yb/Tm (see picture).
