TOC: Images of polished MgO:x%Ni2+, y%Cr3+ (x = 0-0.7, y = 0 and 0.3) ceramics under natural light and NIR-II output power of laser-driven NIR-II device based on MgO:x%Ni2+, 0.3%Cr3+ (x = 0.1-0.7) ceramics under different incident blue laser power densities. This work paves a new avenue for the future development of high-performance Ni2+-activated NIR-II emissive luminescence ceramics for laser-driven non-destructive real-time high-power NIR-II imaging and detection applications.
