核壳III-V族半导体纳米晶体的多步连续生产仍然是一个技术挑战。我们提出了一种新设计的高温微型连续搅拌釜级联反应器，用于连续和可扩展地合成 InP/ZnS 核壳量子点，与涉及 (TMS)3P 的标准方案相比，具有更安全的氨基膦前体。所得的 InP/ZnS 量子点的发射波长在 520 至 610 nm 之间，发射线宽在 46-64 nm 范围内，光致发光量子产率高达 42%。
The multistep and continuous production of core–shell III–V semiconductor nanocrystals remains a technological challenge. We present a newly designed high-temperature and miniature continuous stirred-tank reactor cascade, for the continuous and scalable synthesis of InP/ZnS core–shell quantum dots with a safer aminophosphine precursor comparing to standard protocols involving (TMS)3P. The resulting InP/ZnS QDs exhibit emissions between 520 and 610 nm, narrow emission linewidths in the range of 46–64 nm and photoluminescence quantum yields up to 42%.
