Abstract Lanthanide ion (Ln 3+ )‐doped lead‐free perovskites with near‐infrared (NIR) luminescence have promising application prospects in environmentally friendly photonic devices. It remains a challenge to enhance the photoluminescence quantum yield (PLQY) of Ln ‐doped due their poor light absorption and low energy transfer efficiency. Herein, highly efficient NIR emission is achieved through co‐doping Yb Bi CsMnCl 3 perovskites. Theoretical experimental results demonstrated that attributed additional intense absorptions at 330 nm local symmetry breaking lattice upon ions, which optimize process between ‐Mn 2+ ‐Yb . The PLQY optimized : /Yb emitter reaches 59.8% under UV excitation, highest reported value among Furthermore, benefiting from Mn visible region, can also be excited using low‐energy sources, providing general strategy unlock excitable emitters. Based on its excellent luminescent properties, perovskite has versatile fields such as latent fingerprint detection, night vision, biological imaging.
