Hexagonal NaYF4∶ Yb/Er microcrystals were prepared by a facile trisodium citrate-assisted hydrothermal method. The microparticles were characterized by TEM,X-ray diffraction(XRD),and luminescent spectra. Intense green upconversion luminescence was observed under 980 nm excitation. By introducing Ca2+ dopants into the grain lattices,the upconversion luminescence intensity of NaYF4∶ Yb/Er microcrystal was improved significantly. The enhancement is proposed to originate from a modification of the crystal structure and an improvement in the crystallinity of NaYF4∶ Yb/Er microcrystals.
