	1	Effect of alkaline metal ions on the photoluminescence properties of Eu^(3+)-doped Ca_3Al_2O_6 phosphors显示文摘Ca_3–xAl_2O_6:x Eu^(3+)(0.02≤x≤0.10) and Ca_(2.92)Al_2O_6:0.04Eu^(3+),0.04M^+(M^+=Li^+, Na^+, and K^+) phosphors were prepared by sol-gel method and their photoluminescence properties were investigated. The crystal structure of the annealed Ca_3–xAl_2O_6:x Eu^(3+) and Ca_(2.92)Al_2O_6:0.04Eu^(3+),0.04M^+ phosphors was analyzed with X-ray diffraction(XRD). The size and morphological characteristics of the annealed phosphors were investigated with a field emission scanning electron microscope(FE-SEM). The photoluminescence properties were evaluated with a spectrofluorometer. The phosphors were effectively excited by the light of 396 nm and showed intense red emission at 616 nm, which originated from the 5D_0→7F_2 transition of Eu^(3+). Among the prepared phosphors, the Ca_(2.96)Al_2O_6:0.04Eu^(3+) phosphor showed the strongest emission intensity and the highest color purity. The addition of alkaline metal ions(Li^+, Na^+, and K^+) to Ca_(2.96)Al_2O_6:0.04Eu^(3+) phosphor degraded the emission intensity and color purity.
