High-Performance PbSe Quantum Dots with Palmitoyl Chloride and Their Application to Short-Wavelength Infrared Photodetector Devices.

ABSTRACT: Quantum dots (QDs), particularly those in the short-wavelength infrared (SWIR) range, have garnered significant attention for their unique optical and electrical properties resulting from 3D quantum confinement. Among the various chalcogenide-based QDs, lead chalcogenides, such as PbS and PbSe, are extensively studied for infrared photodetection applications. While PbSe QDs offer advantages over PbS, including a narrower bandgap and higher carrier mobility, they suffer from stability issues due to surface oxidation and particle aggregation. Conventional synthesis methods require additional post-synthesis treatments for surface passivation with halides, which complicates the process. In this work, a novel synthesis approach that incorporates palmitoyl chloride (PalCl) into the traditional P
