摘要

通过钙钛矿纳米晶转换制备PbS量子点在文章2402740中，唐浩东，唐军，郑克玉，陈伟等人提出了一种以钙钛矿纳米晶为先导体制备高质量PbS量子点的钙钛矿转换方法。该方法通过降低陷阱密度和增强载流子输运来提高量子点性能，在SWIR光电探测器中证明，与传统的热注入方法相比，该方法具有更高的响应率和探测率。

Converting Perovskite Nanocrystals to PbS Quantum Dots Toward Short-Wave Infrared Photodetectors (Advanced Optical Materials 7/2025)

PbS QDs via Perovskite Nanocrystal Conversion

In article 2402740, Haodong Tang, Jun Tang, Keyu Zheng, Wei Chen, and co-workers present a novel perovskite conversion method (PCM) for fabricating high-quality PbS quantum dots (QDs) using perovskite nanocrystals (PeNCs) as lead precursors. The method improves QD performance by reducing trap density and enhancing charge carrier transport, demonstrated in SWIR photodetectors with significantly higher responsivity and detectivity compared to conventional hot injection methods.
