Abstract Revealing the energy transfer (ET) process from excitons to rare earth ions in halide perovskites has great guiding value for designing optoelectronic materials. Here, multiple ET channels multi‐exciton emissive Sb 3+ /Nd co‐doped Cs 2 ZrCl 6 are explored comprehend processes. Förster–Dexter theory reveals that sensitizer concentration rather than overlap integral of spectra plays leading function comparison efficiency among host self‐trapped (STEs) and dopant triplet STEs Nd ions. Besides, enables varied color delivery potential as anti‐counterfeiting material. Under X‐ray irradiation, presents a high light yield ≈13300 photons MeV −1 promising imaging ability. This work provides new insight investigating processes potentiality fields imaging.

Published: June 9, 2024

Abstract Rare‐earth based double perovskites (DPs) have attracted much attention due to stable, efficient, and unique luminescence, wide applications in many optoelectronic fields. However, their weak near‐infrared (NIR) emission poor anti‐thermal quenching severely limit the further applications. Herein, Sb 3+ ‐doped Cs 2 KYbCl 6 DP with cyan self‐trapped exciton (STE) NIR is prepared by a solvothermal method, separate photoluminescence quantum yields from STE reached ≈26.1% 43.8%, respectively. More importantly, not only contributes absorption energy transfer but also helps establish an effective thermally enhanced channel through self‐trapping state, resulting superior resistance. The thermal sensitivity of luminescence intensity ratio (LIR) I 1010 nm / 505 ( PL) time‐resolved temperature sensor reach 21.4 13.6% K −1 , respectively, which are ahead most sensing materials. Furthermore, it found that material exhibited advanced multifunctional LED lighting, flexible luminescent thin film, imaging. This work provides in‐depth understanding on photophysical mechanisms rare‐earth materials references for designing high‐performance
