摘要
(Figure Presented) Changing shapes: Metastable spherical aggregates of gold nanoparticles undergo a one-to-one, thermally induced transformation into heterodimers comprising connected plate and spherical domains. By controlling the reaction time, it is possible to isolate a variety of structures differing in the relative sizes of the domains and in the overall optical properties (see picture). © 2007 Wiley-VCH Verlag GmbH & Co.
