Abstract

This work focuses on the synthesis and characterization of 3-mercaptopropionic acid-capped PbSe nanocrystals (NCs) using an aqueous synthetic protocol. The synthesis was carried out at room temperature and resulted in uniform NCs. The as-synthesized NCs were characterized using photoluminescence spectroscopy, HR-TEM and X-Ray diffraction. They showed a perfect Gaussian peak at 1203nm with average diameters of ≤3nm and diffraction patterns consistent with rock-salt structure of PbSe NCs.
