Developing phosphors with narrow photoluminescence emission peaks and high chromatic stability holds significant importance in light-emitting diode (LED) display technologies, where a wide color gamut is essential to achieve the Rec. 2020 specifications. This research focuses on the optical properties of a solid solution: MI2.97Eu0.015MIIIP3O9N [MI = Na, K; MIII = Al, (Al0.75Ga0.25), (Al0.5Ga0.5), (Al0.25Ga0.75), Ga, (Ga0.75In0.25), (Ga0.5In0.5)] to understand how the narrow-emitting photoluminescence in K3AlP3O9N:Eu2+ can evolve during host structure cation substitution. Photoluminescence measurements at low temperature (15 K) support that Eu2+ replaces three crystallographically independent Na+ sites in Na2.97Eu0.015AlP3O9N, similar to the parent K+ phosphor, but substituting Ga3+ and In3+ for Al3+ leads to a change in Eu2+ site preference, narrowing the full-width-at-half-maximum (fwhm) of the emission peak. The chromatic stability and photoluminescence quantum yield are also enhanced with higher Ga3+ content in the host but not with In3+. Thermoluminescence analysis indicates the relationship between trap states and the enhanced quantum yield with Ga3+ leads to the series’ best performance. The analysis of the MI2.97Eu0.015MIIIP3O9N series offers insight into the potential method for modulating optical properties with cation substitution in the host structure.
