Oil-dispersible 
-NaYF4 spherical nanoparticles and 
-NaYF4 hexagonal-shaped nanoplates weresynthesized by the liquid-solid two-phase approach at different reaction temperatures. The TEM andFE-SEM images reveal that the nanoplates have a relatively narrow size distribution. In comparison withother methods, pure -NaYF4 hexagonal-shaped nanoplates were prepared under a relatively mild condition.The nanoplates grew at the liquid-solid interface with slow crystallization rate, which may be preferablefor achieving -NaYF4.
