A general strategy for the synthesis of upconversion rare earth fluoride nanocrystals via a novel OA/ionic liquid two-phase system

Abstract

Herein we report a general strategy to synthesize highly uniform and monodisperse rare earth fluoride nanocrystals through a novel OA/ionic liquid two-phase system, while water-soluble hexagonal NaREF(4) nanocrystals are obtained by adding n-octanol.
