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%.

多步合成InP / ZnS量子点的高温连续搅拌釜反应器级联

核-壳III-V半导体纳米晶体的多步连续生产仍然是一项技术挑战。我们提出了一种新设计的高温微型连续搅拌釜反应器级联，用于连续和可扩展的合成InP / ZnS核-壳量子点，并与涉及（TMS）₃ P的标准方案相比，具有更安全的氨基膦前体。生成的InP / ZnS QD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％。
