摘要

利用再生长方法合成了大尺寸胶体量子点（CQDs）。在掺杂工程的帮助下，合成的 CQD 探测器显示出卓越的长波长红外探测性能，最高可达 18 μm，大大扩展了基于 CQD 的红外探测器的光谱响应极限。这些探测器还实现了 6.6 × 108 琼斯的相当高的探测率。

Extending the detection limit: innovations in infrared quantum dot photodetectors reaching up to 18 μm

A regrowth method was used to synthesize large-sized colloidal quantum dots (CQDs). With the assistance of doping engineering, the synthesized CQD detectors demonstrate exceptional long-wavelength infrared detection performance, reaching up to 18 μm, significantly extending the spectral response limit for CQD-based infrared detectors. These detectors also achieve a reasonably high detectivity of 6.6 × 10⁸ Jones.
