Abstract

•A novel blue-emitting Sr5(BO3)3Cl:Ce3+,Na+ phosphor has been synthesized.•Their structures, luminescent properties have also been investigated.•It exhibits a broad blue emission band peaking at 414 nm with a FWHM of 70 nm.•The CIE coordinates indicates Sr5(BO3)3Cl:Ce3+,Na+ has good color purity.

A novel blue-emitting Sr5(BO3)3Cl:Ce3+,Na+ phosphor was synthesized by solid-state reaction. The excitation spectrum shows a broad band extending from 200 nm to 400 nm, and the emission spectrum shows a broad blue band peaking at 414 nm with a half width of approximately 70 nm. The optimum doping concentration of Ce3+ is found to be 0.7%. The quenching temperature for Sr5(BO3)3Cl:Ce3+,Na+ is 416 K. The calculated CIE coordinates indicate that the phosphor has good color purity. Given their broadband absorption from 250 nm to 400 nm, these phosphors meet the application requirements for GaN-based light-emitting diodes.
