Comparison of the photoluminescence properties of Eu2+, Mn2+ co-doped M5(PO4)3Cl (M=Ca, Sr, Ba)

•Good size match between the doped and host cations narrows the emission band.•Low phonon energy of the hosts enhances the luminescence intensity.•“Inverse bottleneck effect” related to Eu/Mn lifetime mismatch causes quenching.•“Charge transfer process” in the Eu–Mn clusters causes quenching. Eu2+ a...
