An efficient and convenient one-step process was developed for synthesizing new effective red luminous materials through ordered mesoporous γ-alumina assembling with Eu3+. Employing P123 as a structure-directing agent and hydrochloric acid, citric acid as pH adjustor, ordered mesoporous γ-alumina was fabricated by simple sol-gel method. The pore structure was characterized by X-ray diffraction (XRD), N2 adsorption-desorption isotherms and transmission electron microscopy (TEM). The as-synthesized γ-aluminas had narrow pore-size distribution (5-7 nm), large surface area (246 m2/g) and high thermal stability (750-1000 oC). The luminous property of materials was characterized by Photoluminescence (PL) spectra. The γ-Al2O3:Eu3+ materials had efficient luminescence, and the emission strength was related to the content of Eu3+.
