Summary: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 Ba3P5N10Br:Eu2+. Upon excitation by near‐UV light, natural‐white‐light luminescence was detected. The synthesis of Ba3P5N10Br:Eu2+ was carried out using the multianvil technique. The crystal structure of Ba3P5N10Br:Eu2+ 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 Ba3P5N10Br:Eu2+, we have shown the great potential of nitridophosphate zeolites to serve as high‐performance luminescence materials. Unter Druck: Ein Nitridophosphat‐Zeolith der Zusammensetzung Ba3P5N10Br wurde unter hohem Druck (1 bis 5 GPa) und bei hoher Temperatur (1000 °C) synthetisiert und röntgenkristallographisch untersucht (siehe Bild; Br violett, Ba grau, PN4‐Tetraeder grün). Dotierung mit Eu2+‐Ionen ergibt eine natürliche Weißlicht‐Lumineszenz bei Anregung mit Nah‐UV‐Licht.
