Photoluminescent properties of a new blue emitting Ce3+-doped borofluoride phosphor

- The novel blue luminescent Ba3Sr4(BO3)3F5: Ce3+, Na+ phosphor was synthesized.
- The concentration quenching mechanism of Ce2+ ions in this host was investigated.
- The thermal quenching and charge compensation effect were also discussed.
- Ba3Sr4(BO3)3F5: Ce3+, Na+ could be a potential blue phosphor for UV LEDs.
