PbS NANOPARTICLES IN MESOPOROUS TiO_2 FILMS: MONITORING BY POTENTIODYNAMIC ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY

摘要

PbS nanoparticles were introduced into mesoporous TiO_2 films on ITO support by successive ion layer adsorption and reaction (SILAR) and photochemical deposition. Potentiodynamic impedance spectra can be discriminated between PbS nanoparticles bound to ITO support directly and via oxide. This provided monitoring of electrical interconnections in nanostructures of different origins.
