Near-infrared circularly polarized luminescence enabled by chiral inorganic nanomaterials

Abstract

Near-infrared circularly polarized luminescence (NIR-CPL) has attracted widespread attention owing to its fascinating characteristic—circular polarization in specific illumination regions—offering advances in applications such as information security and cancer detection. For the generation of NIR-CPL, chiral inorganic nanomaterials have emerged as the desirable candidates due to their extraordinary chiroptical properties. In this mini-review, we first highlight the recent advances in NIR-CPL produced from chiral inorganic nanomaterials. Thereafter, we present the applications of NIR-CPL in information security and cancer detection. Finally, we prospect the challenges in this field and provide new perspectives and insights for the development of novel NIR-CPL materials and new applications.
