Nonstoichiometric Defect Engineering in Mn<sup>2+</sup>-Doped MgGa<sub>2</sub>O<sub>4</sub> Persistent Phosphors Toward Enhanced Luminescence and Multimodal Optical Manometry. [PDF]
Adv Sci (Weinh)Mg2+ deficiency transforms Mn2+‐doped MgGa2O4 into a multifunctional persistent phosphor, enhancing green emission, thermal stability, and afterglow effect for optical anti‐counterfeiting. Under compression, spectral shifts enable visual pressure sensing with a sensitivity of 5.01 nm GPa−1 over a pressure range up to 30 GPa.
