摘要

Abstract

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 × 10

Jones.
