Hydrothermal synthesis and characterization of LiREF4 (RE = Y, Tb-Lu) nanocrystals and their core-shell nanostructures.
In this paper, a water-ethanol-oleic acid system was developed to prepare LiREF(4) nanocrystals with a controlled size and shape. The influence of LiOH concentration and temperature on the phase and shape evolution of the LiREF(4) nanocrystals was systematically investigated and discussed. It was found that the LiOH concentration was the key factor responsible for the shape evolution and phase control for LiREF(4) nanocrystals at selected temperatures. The LiYF(4)-LiLuF(4) core-shell nanostructure was synthesized and characterized.
