Bright and thermal-stable RGB emission realized by Eu2+-Tb3+/Mn2+ energy transfer in Na3SrMg11(PO4)9

•Structure, site-occupancy and luminescence of Na3SrMg11(PO4)9:Eu2+/Mn2+/Tb3+ were studied.•Broad excitation band and wide-gamut-coverage emission could be achieved by tuning Eu2+/Mn2+/Tb3+ ratio.•The optimal blue/green/red phosphors exhibit high quantum efficiencies with IQE>60%.
