Nanostructures, Optical Properties, and Imaging Application of Lead‐Sulfide Nanocomposite Coatings
Source abstract
Abstract
Lead‐sulfide (PbS) nanocrystals were precipitated in nanocomposite coatings after a pre‐photo‐polymerization followed by a reaction with H 2 S gas at 25°C for 1 hr. PbS nanocrystalline size and optical absorption increased with decreasing UV energy for pre‐photo‐polymerization and increasing concentration. The absorption onset has a large blue shift from 0.41 eV of the corresponding bulk crystal, resulting from the quantum confinement effect. As a result, coating color changes significantly from deep brown to light yellow depending on coating processing conditions. Partially masking the coatings during pre‐photo‐polymerization gives rise to different colors, leading to imaging applications of PbS nanocomposite coatings.
