摘要
The morphology of silver crystals grown at the liquid-liquid interface between silver nitrate and ascorbic acid solutions was investigated in the presence of various organic molecules. The addition of ethylenediamine tetraacetate changed the morphology from dendrites and plates into single-crystalline wires with a width of 100-1000 nm. The wires were produced by elongation and stacking of planar silver crystals exhibiting {111} faces. The anisotropic growth behavior causing the wire formation is tentatively ascribed to stepwise capping of the specific surfaces of silver crystals by organic molecules having multiple carboxyl groups.
