摘要 |
To provide a method of producing Prussian blue-type metal complex nanoparticles without necessarily requiring complicated steps and an excessive amount of raw materials, but allowing one to obtain nanometer-size fine particles having desired fine particle properties, and Prussian blue-type metal complex nanoparticles obtained by the method, a dispersion of the nanoparticles, a method of regulating the color of the nanoparticles, and an electrode and a transmitted light-regulator each using the nanoparticles; Prussian blue-type metal complex nanoparticles are produced by: mixing an aqueous solution containing a metal cyano complex anion having predetermined metal atom MA as a central metal and an aqueous solution containing a cation of predetermined metal atom MB, thereby precipitating the crystal of a Prussian blue-type metal complex having the metal atom MA and the metal atom MB; and then mixing the Prussian blue-type metal complex with an aqueous solution containing a metal cyano complex anion having the metal atom MC as a central metal and/or an aqueous solution containing a cation of the metal atom MD. The thus-obtained Prussian blue-type metal complex nanoparticles have a preferable electrochemical responsiveness, and the particles can be used for forming a thin film including them to construct a light-transmitted regulator.
