| 摘 要： | A series of SrIn2 O4 :Eu3+ phosphors are synthesized by a high temperature solid-state method, and their luminescent properties are investigated. They can be excited by 395-nm radiation, and produce red emission (619 nm); however, they have a low absorption of near-ultraviolet light with the wavelength of 400nm-405 nm. When co-doped with A+ (A=Li, Na, K), the emission intensity of SrIn2O4 :Eu3+ is significantly enhanced, but its emission and excitation spectral profile is unchanged. With co-doping Sm3+ , not only is the emission intensity of SrIn2 O4 :Eu3+ enhanced, but also the absorption is broadened and strengthened in the range of 400 nm-405nm. The effect of Sm3+ -doped content on the emission intensity of SrIn2O4 :Eu3+ , Sm3+ is investigated, and the optimal Sm3+ content is 0.02 mol.
