Paper Abstract

Rare-earth doped NaLaF4 nanocrystals were synthesized by solvothermal method in ethanol/oleic acid/water reaction system. The structure and porphology of samples were characterized by X-ray diffraction(XRD), scanning electron microscopy (SEM) and transmission electron microscopy(TEM). By adjusting the amount of NaOH in the precursor, we obtained NaLaF4:Er3+/Yb3+/Gd3+nanocrystals with a rich variety of morphologies, including nanoprisms, nano-dumbbells, nanorods and nanowires. A possible mechanism of formation of the NaLaF4 nanocrystals was proposed based on the time dependent experiments. The upconversion luminescence properties of rare-earth doped NaLaF4 nanocrystals with different morphology was discussed. The experimental results demonstrated that the NaLaF4:Er3+/Yb3+/Gd3+ nanocrystals with different morphologies exhibited similar up-conversion luminescence, with sharp emission peaks near 540 nm and 650 nm, and red color stronger than green light.
