Ba 3 P 5 N 10 Br:Eu 2+ : A Natural‐White‐Light Single Emitter with a Zeolite Structure Type

Illumination sources based on phosphor‐converted light emitting diode (pcLED) technology are nowadays of great relevance. In particular, illumination‐grade pcLEDs are attracting increasing attention. Regarding this, the application of a single warm‐white‐emitting phosphor could be of great advantage. Herein, we report the synthesis of a novel nitridophosphate zeolite Ba 3 P 5 N 10 Br:Eu 2+ . Upon excitation by near‐UV light, natural‐white‐light luminescence was detected. The synthesis of Ba 3 P 5 N 10 Br:Eu 2+ was carried out using the multianvil technique. The crystal structure of Ba 3 P 5 N 10 Br:Eu 2+ was solved and refined by single‐crystal X‐ray diffraction analysis and confirmed by Rietveld refinement and FTIR spectroscopy. Furthermore, spectroscopic luminescence measurements were performed. Through the synthesis of Ba 3 P 5 N 10 Br:Eu 2+ , we have shown the great potential of nitridophosphate zeolites to serve as high‐performance luminescence materials.
