Preparation of silver dendritic nanostructure using electrochemical deposition and their optical properties

In this paper, two-dimensional silver dendriticlike nanostructure with controllable shape and size was prepared on the surface of ITO conductive glass using electrochemical deposition method. It is shown that voltage is essential to control figure size of the dendritic structure. Insulated film was supported on the silver dendritic structure by electrochemical method and combined with the nondepositional structure aspectantly to form 'sandwich' configuration. We found that the sample prepared at 0.9V can absorb different light wave between 360 nm and 800 nm, and the transmission curves present a serration. This special behavior of transmission is likely as the result of electromagnetic respondence.
