【Abstract】 Nano Y₂O₃:Eu³⁺ fluorescence powder was prepared by thermal decomposition of the rare earth citric acid complexes.The structure,size,morphology and luminescent properties of fluorescence powder were investigated by means of XRD and TEM.The results show that the crystal structure of nano Y₂O₃:Eu³⁺fluorescence powder is cubic,and the size of the particles is between 20 nm and 60 nm.The phosphors has the maximum excitation peak at 248 nm,and the maximum emission peak at 615 nm.更多还原
