Abstract Recently, lead‐free double perovskites have gained much attention for their superior optoelectronic properties. However, realizing efficient white light and near‐infrared (NIR) emission, as well bright radioluminescence (RL) in a single compound has not yet been reported. Herein, Bi 3+ /Mo 4+ ‐codoped Cs 2 Ag 0.6 Na 0.4 InCl 6 perovskite is synthesized by hydrothermal reaction. Under photoexcitation, the codoped exhibits highly broadband warm‐white emission (610 nm) NIR (930 nm), which can be attributed to self‐trapped exciton of d–d transition Mo , respectively. Interestingly, also emits strong with yield 25100 photons per MeV under X‐ray irradiation. Based on /PDMS flexible film, its applications emitting diodes (WLED), source, scintillator are demonstrated, respectively, all exhibit remarkable Finally, as‐fabricated devices light, NIR, imaging further demonstrated pixel‐level image fusion realized without pixel mismatch complex processing. Therefore, internal information capsule wrapped centrifuge tube iron wire successfully through fusion.
