Longitudinal shape evolution of Ag2S nanoparticles from nanospheres, rhombic dodecahedrons, nanorods, to nanocubes

Author affiliations

Abstract

Longitudinal shape evolution of Ag2S nanoparticles is reported. Initially 9 nm nanospheres turn into faceted rhombic dodecahedrons and elongate to minimize surface energy. The elongated rhombic dodecahedrons show oriented attachments to 〈−104〉 directions sequentially yielding dimers, linear oligomers, and nanorods. Lateral sides of nanorods fuse to thermodynamically stable nanocubes upon ripening.
