Near‐Infrared Emission Perovskites for Multifunctional Bioimaging
2025
Overview
Bioimaging with remarkable noninvasive nature, ultrahigh resolution and sensitivity allows detection of pathologies of bones, organs, and tissues. Nevertheless, the achievement of more complete information in vivo is challenged by the necessity of multiple photodetectors with diverse response ranges. Herein, a multifunctional bioimaging with Cs2AgInCl6:Yb3+ perovskites via a single InGaAs detector for superior tissue presentation is realized in this work. Co‐incorporation of foreign dopant contributes to alterations of local structural symmetry of the Cs2AgInCl6 host, disruption of parity‐forbidden transitions, and reduction in electron–phonon coupling strength, thereby boosting the near‐infrared (NIR) intensity by 40‐fold of the corresponding perovskites drastically. Moreover, an X‐ray excited NIR light output is 2.83 times that of commercial Bi4Ge3O12 scintillators. Thanks to the efficient NIR emission, the versatile perovskites film endows a multifunctional bioimaging with detailed information of biological tissue in vivo, which fundamentally offers viable avenues for promoting bioimaging technology with integrated access of tissue presentation. Currently, the acquisition of information inside living organisms is highly dependent on a variety of photodetectors with different response ranges, for which a near‐infrared‐emitting perovskite material has been designed that exhibits excellent performance under both UV and X‐ray irradiation, enabling multimodal imaging of biological tissues with only one InGaAs detector.
