Abstract

The up-conversion NaGdF

nanocrystals were successfully prepared by hydrothermal method. The samples were characterized by X-ray powder diffraction (XRD)

scanning electron microscopy (SEM) and luminescence spectra. The crystal structure and morphology can be well controlled by adjusting the molar ratio of

and GdF

samples exhibit green(541 nm)and red(647 nm)emissions under 980 nm excitation

which are assigned to the transition of

respectively. It was found that the upconversion efficiency of the hexagonal prism and flake NaGdF

∶Yb

samples are much stronger than that of GdF

∶Yb

samples

but the spherical NaGdF

∶Yb

samples are weaker than GdF

∶Yb

samples. This indicates that the upconversion efficiency of hexagonal NaGdF

∶Yb

samples are greatly impacted by the different size and crystalline for different morphology.
