Abstract EN
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 NaBF4 was 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 GdF3 nanocrystals and the possible reasons of the strong PL in hexagonal were discussed.
