| Research Abstract |
Co nanoparticles were deposited on a substrate in an island pattern using an arc plasma gun (APG). Then, a MgO thin film was formed on this substrate by metal organic decomposition (MOD), which enables the formation of films in atmosphere, thus yielding a double-layer structure. The MgO thin film on Co nanoparticles deposited using the APG with 500 pulses of arc discharge exhibited improved crystallinity and a photoelectron emission that was at least threefold higher than that of the MgO thin film without Co nanoparticles. Although the transmittance of the specimen, formed by depositing Co nanoparticles on a Si substrate with 500 pulses of arc discharge, was 30% or lower, it increased to higher than 90% after the formation of a MgO thin film on the substrate and the dispersion of the Co nanoparticles within the MgO thin film during heat treatment at 900 °C. Thus, a highly transparent film was obtained.
