Silver Selenide Colloidal Quantum Dots for Mid-Wavelength Infrared Photodetection
Abstract
Lately discovered silver selenide (Ag 2 Se) colloidal quantum dots with tetragonal crystal structure exhibit promising optical properties in the mid-wavelength infrared. Although colloidal synthesis of uniform sizes and shapes as well as detailed phase transformation and photoluminescence properties have been studied recently, investigations of their optoelectronic properties as an active layer in photodetector devices remain scarce. Herein, we present the fabrication and characterization of Ag 2 Se colloidal quantum dot-based photoconductive photodetectors. We investigate the effect of ligand exchange as well as temperature and spectral-dependent photoresponses. Our results suggest that further enhancement in performance could be achieved through accurate control of carrier concentration. With this improvement, Ag 2 Se colloidal quantum dots may serve as a promising mid-wavelength infrared absorber for the development of thermal infrared sensors and imagers with low size, weight, power consumption, and cost.

Ag2Se QDs rely on intra-band absorption.
“Ag2Se QDs, which rely on intra-band absorption, is thereby the more attractive material because of the greatly reduced toxicity.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
