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.

Abstract Lead‐free double perovskites (LFDP) have attracted considerable attention due to their remarkable optoelectronic characteristics, which include tunable bandgaps spanning the entire visible spectrum, high photoluminescence quantum yields (PLQY), and wide emission bandwidths. The incorporation of transition metal ions into lead‐free perovskites, as an efficient method for tailoring optical properties, is crucial both foundational research practical applications in devices such light‐emitting diodes (LEDs), anti‐counterfeiting, temperature sensors, X‐ray scintillators. In this review, recent progress design ion‐doped summarized, briefly introduce strategies effective doping several representative perovskites. manipulation properties through ion doping, focusing on enhanced stability, increased luminescent efficiency, tuning bands, luminescence lifetimes are highlighted. conclusion, challenges perspectives dynamic area addressed.
