Preparation and properties of rare earth dopedfluoride powders
Abstract ：In recent years with luminescent materials development and application of variousadvanced fluorescence detection techniques and instruments, fluorescent material has begun tosuccessfully applied to high sensitivity of detection of biological and bio imaging field. In viewof this, hydrothermal synthesis of KY3F10 nanometer luminescent materials is used in thisthesis, and the luminescent properties of the luminescent materials are studied.. 16h nano -phosphors were synthesized by hydrothermal method at 210, KY3F10,, Sm3+, Tb3+ rare earthion and Sm3+, Tb3+, and the co - doped phosphors were prepared.. X ray diffraction (XRD)was used to analyze the samples, the results showed that the samples were pure KY3F10.Photoluminescence (PL) spectra of the tests show that, we successfully synthesized thefluorescent powder of green, red and orange
