    摘要: An optical apparatus includes a first electrode that can be kept in a transparent state in a visible light region, and a second electrode electrically separated from the first electrode. A space is provided between the first and second electrodes. A certain function is used to provide a driving potential to the first and second electrodes. An electrolyte is poured into the space between the electrodes. The electrolyte is composed of a solution prepared by dissolving a silver salt in at least one type of solvent selected from a group consisting of dimethylformamide, diethylformamide, N, N-dimethylacetamide, N-methylpropionamide, N-methylpyrrolidone, 2-ethoxyethanol, and 2-methoxyethanol. By use of this electrolyte, silver is precipitated and dissolved under driving control over the first and second electrodes. As a result, color-developing and color-fading are effected by precipitation and dissolution of silver, respectively.

    摘要: An optical device is provided as an optical filter including a pair of substrates at least one of which is transparent, at least one transparent electrode disposed on one side of the transparent substrate, at least one counter electrode, a spacer provided between a pair of the substrates at peripheries thereof, and an RED solution as a filtering material provided in a space between a pair of the substrates. The RED solution includes a silver salt and a mixed solvent, preferably DMSO and another solvent, for dissolving the silver salt. The transparent electrodes and the counter electrode are driven by applying a voltage thereto, and the silver salt is reversibly deposited and dissolved by controlling the voltage. The RED solution is brought to be colored and to be colorless, respectively, so that an amount of light passing through the device may be adjusted.
