چکیده انگلیسی
Ultra-thin (0.5-5Â nm) films of Ag have been prepared by pulsed laser deposition in vacuum using a 26Â ns KrF excimer laser at 1Â JÂ cmâ2. The deposition was controlled using a Langmuir ion probe and a quartz crystal thickness monitor. Transmission electron microscopy showed that the films are not continuous, but are structured on nanometer size scales. Optical absorption spectra showed the expected surface plasmon resonance feature, which shifted to longer wavelength and increased in strength as the equivalent film thickness was increased. It is shown that Maxwell Garnett effective medium theory can be used to calculate the main features of optical absorption spectra.
