| Abstract: | Monodisperse silver nanocubes with edge length of 55 +/- 5 nm were, for the first time, synthesized in water on the basis of HTAB-modified silver mirror reaction at 120 degrees C (HTAB, n-hexadecyltrimethylammonium bromide). The individual nanocube was crystallographically well defined with a single crystal bonded by six {200} facets. The nanocubes were soluble to form stable aqueous solutions and had a strong tendency to assemble into two-dimensional arrays with regular checked pattern on substrate. |
