摘　　要：A storage and emission functional material of [Ca24Al28O64]^4＋·（Cl^-）3.80（O^2-）0.10 （C12A7-Cl^-）, was prepared by the solid-state reactions of CaCO3, γ-Al2O3, and CaCl2 in Cl2/Ar mixture atmosphere. The anionic species stored in the C12A7-Cl^- material were dominated by Cl^-, about （2.21±0.24） × 10^21 cm^-3, accompanied by a small amount of O^2-, O^-, and O2^-, measured via ion chromatography, electron paramagnetic resonance, and raman spectra measurements. These results also corroborate identification of time-of-flight mass spectroscopy--the anionic species emitted from the C12A7-Cl^- surface were dominated by the Cl^- （about 90%） together with a small amount of O^- and electrons. The structure and morphological alterations of the material were investigated via X-ray diffraction and field emission scanning electron microscope, respectively.
