Green synthesis of upconversion nanocrystals by adjusting local precursor supersaturation under aqueous conditions
We describe a green synthesis of upconversion nanocrystals (UCNs) by adjusting local precursor supersaturation under aqueous conditions at low temperature with size and phase control as well as high production yield. The synthesis allows the separation of nucleation and growth, leading to the format...
