From XPS, it was suggested that an optoelectronic coreshell interfacial interaction might depress the coherent cooperative drift motions of excited electrons, i.e., LSP. © 2005 Old City Publishing, Inc. 关键词: Nanostructured materials;Crystals;Surface plasmon resonance;Drift chambers;Excitons;Absorption;Polydiacetylene;Co-reprecipitation method;Hybridized nanocrystals;Localized surface plasmon;XSP
