The coordination compound was prepared by Y~(3+), Yb~(3+) , Er~(3+) ions and edta. The precursor was synthe-sized via precipitation-coordnation equilibrium including RE coordination compound and fluorin ion. Upconversion lumines-cence in Yb~(3+) , Er~(3+):YF_3 nanoerstalcine powers excited by a 980 nm laser diode had synthesized by crystallizing precursor in 240℃ hydrothermal condition. The TEM revealed that most of paryicles were nearly spherical and average diameter of the particles was in the range of 30～50nm.
