Abstract

GdF3:Eu3+nanophosphors with hexagonal or orthorhombic structure have been succeeded to be selectively synthesized at room temperature for the first time via a simple soft chemical route. The structure and morphology of GdF3:Eu3+nanophosphors were controlled by using different fluoride precursors. Hexagonal GdF3:Eu3+nanocrystals were formed when NaBF4was used as a fluoride precursor, while orthorhombic GdF3:Eu3+nanocrystals were obtained with NaF or NH4F fluoride precursor. It was also experimentally revealed that hexagonal GdF3:Eu3+nanophosphors emitted essentially stronger Eu3+luminescence than orthorhombic ones did. The formation mechanism of GdF3nanocrystals and the possible reasons of the strong PL in hexagonal were discussed.
