Abstract	The phosphors Sr6Lu2-2xAl4O15:xTb3+ were synthesized through the solid-state reaction technique. The structure,photoluminescence properties and concentration quenching mechanisms were researched. The depen⁃ dence of photoluminescence intensities on Tb3+ concentration was studied. Upon excitation with UV excitation,when the doping concentration x=0. 01,the strongest peak located around 381 nm,which arise from 5D3-7F6 transition of Tb3+；when the doping concentration x=0. 15,the strongest peak located around 545 nm,which arise from 5D4-7F5 transition of Tb3+. The luminescence color changes from blue to yellowish green by adjusting the doping concentration of Tb3+. The concentration quenching mechanisms of Sr6Lu2-2xAl4O15:xTb3+ were studied. The lifetime,thermal sta⁃ bility and quantum efficiency were measured. The Sr6Lu2-2xAl4O15:xTb3+ phosphor is a novel color-tunable phosphor. © 2023 Chines Academy of Sciences. All rights reserved.
