Abstract

Using supercritical fluid CO2 (Sc-CO2) as a medium, PbS nanoparticles can be uniformly deposited on surfaces of various substrates. Sc-CO2 deposition of PbS nanoparticles on carbon-coated copper grids, into small holes in silicon, and formation of uniform PbS nanoparticle films on glass are described. Fluorescence spectra of PbS nanoparticles obtained from the films prepared by the Sc-CO2 method indicate effective energy transfer between PbS nanoparticles of different sizes.
