Photo-Induced Synthesis of Ytterbium and Manganese-Doped CsPbCl₃ Nanocrystals for Visible to Near-Infrared Photoluminescence with Negative Thermal Quenching.

ABSTRACT: Rare-earth-doped all-inorganic perovskite applications for near-infrared (NIR) emission are crucial for the construction of the next generation of intelligent lighting sources. However, the preparation of rare-earth-doped all-inorganic perovskite is complex, and difficult to control, and the issue of thermal quenching poses significant challenges to its practical application. Here, in order to address these issues, a convenient photo-induced synthesis method for CsPbCl₃:Mn/Yb nanocrystals (NCs) is proposed by decomposing carbon tetrachloride with 365 nm light to provide chloride ions and regulate the formation of perovskite at room temperature. The negative thermal quenching in the NIR emission is achieved through the energy transfer between Mn and Yb. The emission intensity of
