Abstract

The invention provides a rare earth Dy<3+>-doped indium tungstate nano material, a preparation method and application thereof. The nano material is shaped as uniform nano-rods, and the molar percentage of Dy<3+> doping is 1% to 12%. The preparation method comprises the following steps: proportionally dissolving InCl3, Na2WO4.2H2O and Dy(NO3)3.5H2O in an organic solvent, then adding tetrabutylammonium bromide and mixing evenly, adjusting pH value of the system to 7.0-9.0 by using n-propylamine, carrying out a thermostatic reaction at 170-190 DEG C for 8-20 hours, and postprocessing after the reaction. The molar ratio of the total amount of InCl3 and Dy(NO3)3.5H2O to Na2WO4 is 2:3. The nano material of the invention has advantages of simple preparation method, good morphology reproducibilityand good luminescence performance.
