Abstract

A method for preparation of optical thin film with nanophase silver particles dispersed in nickel oxide belonged to the composite material field of nanophase metallic particles and inorganic non-metallic material. The precursor solution is prepared by sol-gel processing, the raw material is the silver nitrate and the nickel nitrate that its concentration is 0.2-1mol / L, the dissolvent is the ethylene glycol monomethyl ether, the mole ratio of the silver nitrate and the nickel nitrate is 0.007:1-2.769:1;The thin film is produced by the even pastern machine, the art work is simple, the price is low, the reaction temperature is 200DEG C-900DEG C which is lower than classical sintering methods, the components of the thin film is easy to control, the cycle of the production is shorter, and the enenry is saved. The non-linear optical thin film with nanophase silver particles dispersed in nickel oxide produced in the invention has the perfect non-linear optics characteristic that the absorption peak can be observed in condition of the specified wavelength, it has broad application foreground in the aspect of the optical device such as the optical switch, the optical computer and the optical wave separator. The content of Ag in the coextruded film attains 80wt % at most.
