Preparation of Y2O3 Nanocrystals and its properties

Abstract

Well-dispersed Y2O3:Eu nanocrystals with size less than 10 nm can be synthesized by a simple organometallic route. Two strong emission peaks located between 610 and 630 nm, and near 2% quantum yield can be achieved under 466 nm excitation. Excellent dispersibility and long emission life time would be a allow Y2O3:Eu nanocrystals to used as biological labeling. In addition, Y2O3:Eu nanodisks are obtainable under different experimental conditions, which may find some applications in future nano-devices.
