摘要：

Herein, we report the synthesis and luminescence properties of Tb-doped layered per-ovskite oxychloride, Ba3Y2O5Cl2. Similar to Ba3Y2O5Cl2:Eu3+, single-phase Ba3Y2O5Cl2:Tb3+ was successfully synthesized through a solid-state reaction. The luminescence properties were studied and compared with those of Y2O3:Tb3+. There was only one excitation peak due to the 4f-5d transition of Tb3+, which was different from that of Y2O3:Tb3+ that comprises two peaks. Green emissions from Tb3+ 4f-4f transitions were observed for both the samples. The luminescence properties at different doping concentrations were investigated. Concentration quenching at 8% was found, which is rather high, owing to the specially separated layered structure. The decay times of luminescence were also studied, which are consistent with the concentration quenching. In addition, energy diagram for the luminescence mechanism were also proposed. Considering the photoluminescence spectra and high concentration quenching, this compound is a potential mother compound for optical materials, especially for the green phosphors.(c) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
