With the rapid development of markets and economies, various brands have raised higher demands for optical anticounterfeiting technology. Lead-free halide double perovskites with broadband self-trapped exciton emission excellent properties such as good visibility, diverse colors, simple designs, making them outstanding materials information encryption applications. In this study, we successfully synthesized lead-free dual centers by doping Sb3+ Cr3+ into Cs2NaScCl6. The blue (445 nm) originates from [SbCl6]3- octahedra, while near-infrared (980 comes luminescence ions. achieved a quantum efficiency up to 71% through efficient energy transfer among multiple centers. Finally, patterns were realized screen printing samples. research results provide inspiration designing tunable luminescent properties.
