Abstract: Accumulation and relaxation of optically induced electric charge in ZrO$_2$(Y) films with embedded single-layered arrays of Au nanoparticles (NPs) of 2–3 nm in diameter have been studied subject to the depth of the Au NPs in the ZrO$_2$(Y) layers and the optical excitation power at the wavelengths of 473 and 633 nm by Scanning Kelvin Probe Microscopy (SKPM).

Keywords: thin film systems, zirconia, nanoparticles, plasmon resonance.
