Abstract
We demonstrate an strategy for improving the luminescence thermostability by tuning site symmetry in the SrGa<sub>12</sub>O<sub>19</sub>–LaMgGa<sub>11</sub>O<sub>19</sub>:Cr<sup>3+</sup> system. End-member SrGa<sub>12</sub>O<sub>19</sub>:Cr<sup>3+</sup> with 45% EQE has potentials in high-power and efficient NIR pc-LED applications.
