Engineering the synthesis procedure for PbS nanosheets with controlled optical properties in the near-infrared region

Abstract

This work discloses routes of obtaining two-dimensional PbS nanostructures by chemical synthesis methods. Using the techniques of absorption and luminescence spectroscopy, their optical characteristics are revealed. Special attention is paid to the evolution of nanoplates in a colloidal solution. The processes of growth and degradation of the structure of nanoplatelets, as well as the corresponding changes in the optical properties of nanocrystals are considered.
