摘要：
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 mu m, significantly extending the spectral response limit for CQD-based infrared detectors. These detectors also achieve a reasonably high detectivity of 6.6 x 108 Jones.
