在由银（Ag）核和聚二乙炔（PDA）核组成的核-壳型杂化纳米晶体中，银核的局部表面等离子体元（LSP）在固态聚合过程中消失。从同步辐射x射线在SPring-8中测量的高能x射线光电子能谱来看，银核显然是由纳米级导电畴组成的。畴边界可能导致银核中传导电子平均自由程的减小，并且可能在不改变等离子体频率的情况下导致LSP阻尼。(DOI: 10.1380 / ejssnt.2009.711)
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.
