Here we reported the phase formation of M  x  Mg 2 Al 4+ x  Si 5− x  O 18 :Eu 2+  (M = K, Rb) solid solution phosphors, where M +  ions were introduced into the void channels of Mg 2 Al 4 Si 5 O 18  via Al 3+ /Si 4+  substitution to keep the charge balance. XRD results revealed that the as-prepared phosphors with different M +  contents were iso-structural with Mg 2 Al 4 Si 5 O 18  phase. The combined analysis of the Rietveld refinement and high resolution transmission electron microscopy (HRTEM) results proved that M +  ions were surely introduced into the intrinsic channels in Mg 2 Al 4 Si 5 O 18 . The emission peaks of M  x  Mg 2 Al 4+ x  Si 5− x  O 18 :Eu 2+  (M = K, Rb) phosphors with various  x  values performed a systematic red-shift tendency, which was ascribed to the elongation of [MgO 6 ] octahedra. The temperature stable photoluminescence and internal quantum efficiency (QE) of M  x  Mg 2 Al 4+ x  Si 5− x  O 18 :Eu 2+  (M = K, Rb) phosphors were enhanced owing to the filling of M +  in the void channels suggesting a new insight to design the solid solution phosphors with improved photoluminescence properties.
