Abstract

In the core-shell type hybridized nanocrystals composed of silver (Ag)-core and polydiacetylene (PDA)-shell, the localized surface plasmon (LSP) from Ag-core disappeared during solid-state polymerization in the coreprecipitation method. From high-energy X-ray photoelectron spectroscopy measured with synchrotron radiation X-ray in SPring-8, it has become apparent that a Ag-core is composed of nano-sized conductive domains. Domain boundaries may cause the reduction of the conduction electron mean free path in a Ag-core, and may be responsible for LSP damping without changing the plasmon frequency.
