◽
Na (Y1.5Na0.5)F6 microparticks were prepared by hydrothermal method. EDTA as the chelating agent. The samples were characterized by X-ray diffraction, scanning electron microscopy and fluorescence spectrometer. The X-ray diffraction indicates that the crystal shows a hexagon phase structure. Under the excitation of 980nm laser, the Na (Y1.5Na0.5)F6 exhibited strong up-conversion light: 4F9/2→4I15/2(red), 4H11/2/4S3/2→4I15/2(green) and 4G11/2→2H9/2 (near-ultraviolet).
