摘要：In this paper, color-tunable Gd2O2CN2:Tb3+, Eu3+ phosphors were obtained by co-doping Eu3+ and Tb3+ ions into Gd2O2CN2 host and singly varying the Eu3+ doping concentration. The characteristics of the crystal structure, photoluminescence lifetime and photoluminescence of Tb3+, Eu3+ single-doped and Tb3+ and Eu3+ co-doped Gd2O2CN2, were carefully investigated by XRD, FTIR, PL decay curves and photoluminescence (PL). The results indicated that Tb3+ single-doped Gd2O2CN2 phosphor shows a green emission, and by increasing Eu3+ content, Gd2O2CN2:Tb3+, Eu3+ phosphors emit green to orange and then to red light under the excitation of 379 nm.
