Title: The photoluminescence properties of Y{sub 2}O{sub 3}:Eu{sup 3+} prepared by surfactant assisted co-precipitation-molten salt synthesis

Abstract

Y{sub 2}O{sub 3}:Eu{sup 3+} red phosphors were prepared by surfactant assisted co-precipitation-molten salt synthesis method. The effects of surfactant content and annealing temperature on the structure and luminescence were investigated by X-ray diffraction and fluorescence spectrophotometer. The use of surfactant reduces the impurities on the surface of particles and promotes the reaction. The color purity of as-prepared Y{sub 2}O{sub 3}:Eu{sup 3+} red phosphors is improved with the presence of surfactant. In the excitation spectra, two strong bands at 394 and 466 nm are attributed to {sup 7}F{sub 0,1}-{sup 5}L{sub 6}, {sup 7}F{sub 0,1}-{sup 5}D{sub 2} transitions of Eu{sup 3+} ions respectively. With the excitation of 394 or 466 nm, the as-fabricated samples reveal excellent red emission as high as that of samples monitored by 254 nm. Thus, the Y{sub 2}O{sub 3}:Eu{sup 3+} is a promising red phosphor for ultraviolet-visible light-emitting diodes.
