Abstract

Hexagonal-phase NaYF

:Yb

Er/Ho/Tm up-conversion nanocrystals were synthesized using ricinoleic acid (RA) as an sufficient and user-friendly surfactant. The strategy is to form small solid-state crystal nuclei at a lower temperature and then make the nuclei further grow and ripen at a higher temperature. The experiment results show that the structure of NaYF

:Yb

Er/Ho/Tm nanocrystal is hexagonal-phase with the diameter of 45 nm. The nanocrystals show strong luminescence under the excitation of a 980 nm laser with the average power about 1 W. When the nanocrystals are dispersed in the mixed solution of water and dichloromethane

we can only see a strong green bright beam in water

which demonstrates the hydrophilic characteristic of RA-NaYF

nanocrystals. The fluorescence property of NaYF

:Yb

Er/Ho/Tm nanocrystals has no significant change in acidic medium or alkaline.
