[交流] Photophysical, Photochemical and Photocatalytic Aspects of Metal Nanoparticles

Photophysical, Photochemical and Photocatalytic Aspects of Metal Nanoparticles
J. Phys. Chem. B 2002, 106, 7729-7744
Prashant V. Kamat

Unique electronic and chemical properties of metal nanoparticles have drawn the attention of chemists, physicists, biologists, and engineers who wish to use them for the development of new generation nanodevices. Metal nanoparticles such as gold and silver show noticeable photoactivity under UV-visible irradiation as is evident from the photoinduced fusion and fragmentation processes. Binding a photoactive molecule (e.g., pyrene) to metal nanoparticle enhances the photochemical activity and renders the organic-inorganic hybrid nanoassemblies suitable for light-harvesting and optoelectronic applications. The nature of charge-transfer interaction of fluorophore with gold surface dictates the pathways with which the excited-state deactivates. Obtaining insight into energy and electron-transfer processes is important to improve the charge separation efficiencies in metal-fluorophore nanoassemblies and photocatalytic activity of metal-semiconductor composites.

感谢提供资源,但能否请您一并提供相关出处,谢谢
让我与你握别-再轻轻抽出我的手-知道思念从此生根...年华从此停顿-热泪在心中汇成河流-是那万般无奈的凝视...就把祝福别在襟上吧-而明日-明日又隔天涯
