Rare-earth luminescence materials in lighting the tube and the field emission fields has been widely applied.In the leds, special security lights and energy-saving lighting are in the areas of infinite good prospect, this paper the research progress of preparation and a concrete discussion . The ultrasonic method for Y2O3:Eu3+ nanocrystal, annealing conditions on the Y2O3:Eu3+ nanocrystal particles size, crystal condition and the influence of the luminescence properties.The properties of the Y2O3:Eu3+ complexes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Reaction conditions, such as ultrasonic power and the temperature were found to have close relation with the morphologies of final products.
