A large red-shift in the photoluminescence emission of Mg1−xSrxTiO3

- Mg1−xSrxTiO3 powders were successfully synthesized via a polymeric precursor method.
- Structural control of the PL properties of Mg1−xSrxTiO3.
- Our findings thus explain the shift in PL behavior from blue to NIR emission.
- Mg1−xSrxTiO3 powders have potential applications in emerging technologies.
