The equivalent or heterovalent substitution strategy is an efficient way to stimulate photoluminescence tuning or to optimize the luminescence performances of phosphor materials. Garnet-type compounds receive much attention as phosphor hosts because of their flexible structural frameworks. Herein, a garnet-type Lu 2 MgAl 4 SiO 12 :Eu 2+ phosphor with broad-band blue-green emission is first explored with two-site occupation by varying the Eu 2+ content. Two host-substitution approaches to controlling the luminescence behavior of Lu 2 MgAl 4 SiO 12 :Eu 2+ phosphor are implemented. The cation substitution strategy of Ca 2+ for Mg 2+ achieves tunable emission from 463 to 503 nm together with broadening emission bands in Lu 2 Mg 1- y  Ca  y  Al 4 SiO 12 :Eu 2+ phosphors. Moreover, chemical unit cosubstitution of [Ca 2+ -Ge 4+ ] replacing [Lu 3+ -Al 3+ ] results in Lu 2- z  Ca  z  MgAl 4- z  Ge  z  SiO 12 :Eu 2+ phosphors, which induce a red shift of the emission peak of about 60 nm and a broadening in the emission spectra with increasing Ca 2+ and Ge 4+ concentrations. The possible photoluminescence tuning mechanism is ascribed to the coordination sphere variation in the EuO 8 polyhedron depending on the changing neighboring cations. The proposed approaches on equivalent or heterovalent substitution can contribute to the development of Eu 2+ -activated garnet-type phosphors with regulation of the luminescence performance and further initiate research discovering new phosphors for white-light-emitting diodes.
