Abstract The undoped and Eu2+/Ce3+ doped Ca3Li4-ySi2N6-yOy (0≤y≤1.5) (CLSN) were successfully prepared by solid-state reaction and their luminescence properties were studied. The undoped CLSN shows red defect-related luminescence with maximum emission intensity at 710 nm, Eu2+ and Ce3+ doped CLSN also show red emission centered at 702 nm and 673 nm, respectively. The electronic structure and the thermal stability of CLSN were investigated in this work. The results indicate that CLSN:Eu2+/Ce3+ could be conducive to the development of phosphor-converted light-emitting diodes.
