, spectral profile, quantum efficiency, luminescence thermal stability, as well as persistent luminescence and mechanoluminescence), aiming to provide a theoretical basis and experimental guidance for further refinement of chromium-activated phosphors. We also discuss future opportunities and challenges of chromium-activated phosphors, such as extended optical tuning by controlling crystal size and energy level coupling.
