The results showed that Ca19Mn2(PO4)(14): Eu2+ exhibited strong Mn2+ sensitized emission under 360 nm excitation, with excellent emission engineering achieved through Sr2+ co-doping. The phosphor also demonstrated promising thermal stability. Overall, this study highlights the great potential of Ca19Mn2(PO4)(14): Eu2+ phosphor as an efficient red phosphor for phosphor-converted white LEDs.
