Inorganic UV–Visible–SWIR Broadband Photodetector Based on Monodisperse PbS Nanocrystals

Abstract

Solution-processed inorganic UV-visible short-wave-infrared photodetectors with light sensitivity from 350 nm to 2000 nm are fabricated using highly monodispersed large PbS NCs. These devices showed detectivity values over 1 × 1011 Jones from 350 nm to 2000 nm, and a maximum detectivity value of 1.2 × 1012 Jones at 1800 nm.
