Optical characterization of YBa2Cu3O7−δ thin film modified gold nanoparticles
چکیده انگلیسی
We report on the influence of YBa2Cu3O7−δ (YBCO) thin films on the self-organized formation of gold nanoparticles. A thickness variation of the YBCO film allows one to actively control the size of the particles and their density distribution. In this context, the particle forming process is discussed. The YBCO matrix can be removed in order to reduce the particle density on the substrate. The remaining modified particles can be used in plasmonic applications. Combining scanning electron microscopy and dark-field microscopy permits one to identify a correlation of the measured scattering spectra with the physical properties of each studied particle. A clear assignment of spectrum and particle is supported by a new Ti-marker technology and image processing. Growth parameters allow the scientist to tune the spectral peak position of the plasmon resonance and the spectral bandwidth.
