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.
