Embodiment 1

[0015] Dissolve 0.2967g of nickel nitrate in 10ml of ethylene glycol monomethyl ether solvent, and dissolve under magnetic stirring at 10°C for 1 hour to obtain a 0.1mol / L Ni matrix solution. After aging for 2 hours, add 0.0016g of chloroauric acid, Stir magnetically again at 10°C for 1 hour to prepare the Au / NiO precursor solution; before spinning the glue, immerse the substrate in acetone and ethanol for 15 minutes with ultrasonic vibration cleaning, then drop the solution onto the substrate at 300rpm After running for 5 seconds, run at 1000rpm for 10 seconds. After homogenizing the glue once, the film was thermally decomposed at 100°C for 2 seconds, and finally the sample was placed in a heat treatment furnace for 5 minutes for annealing at 200°C to prepare Au 0.01 / Ni 0.99 O composite optical film.

Embodiment 2

[0017] Dissolve 0.8902g of nickel nitrate in 10ml of ethylene glycol monomethyl ether solvent, and dissolve under magnetic stirring at 50°C for 2 hours to obtain a 0.3mol / L Ni matrix solution. After aging for 3 hours, add 0.0429g of chloroauric acid, Stir magnetically again at 50°C for 3 hours to prepare the Au / NiO precursor solution; before spinning the glue, immerse the substrate in acetone and ethanol for 15 minutes with ultrasonic oscillation, then drop the solution onto the substrate and run at 400rpm After 6 seconds, run at 1500rpm for another 12 seconds. Every time the glue is uniformed, the film is thermally decomposed at 200°C for 100 seconds. After 10 times of glueing, the sample is placed in a heat treatment furnace for annealing treatment for 20 minutes. The annealing temperature is 300°C to prepare Au 0.1 / Ni 0.9 O composite optical film.

Embodiment 3

[0019] Dissolve 1.1869g of nickel nitrate in 10ml of ethylene glycol monomethyl ether solvent, and dissolve with magnetic stirring at 40°C for 4 hours to obtain a 0.4mol / L Ni matrix solution. After aging for 5 hours, add 0.3436g of chloroauric acid, Stir magnetically again at 40°C for 5 hours to prepare the Au / NiO precursor solution; before spinning the glue, immerse the substrate in acetone and ethanol for 15 minutes with ultrasonic oscillation, then drop the solution onto the substrate and run at 500rpm After 15 seconds, run at 2600rpm for another 30 seconds. Every time the glue is glued, the film is thermally decomposed at 300°C for 150 seconds. After being glued 20 times, the sample is placed in a heat treatment furnace for annealing treatment for 30 minutes. The annealing temperature is 500°C to prepare Au 0.4 / Ni 0.6 O composite optical film.

Abstract

The invention relates to nanometer gold grain dispersion nickel oxide compound optical thin film manufacturing method. It uses sol-gel method to make Aux/Ni(1-x)O compound optical thin film of which x expresses Au mass percent, is more than 0 and not more than 0.9. The material is gold chloride acid and nickel nitrate of which concentration is between 0.1mol/L and 1mol/L. The solvent is ethylene glycol monoemethyl ether. The invention has the advantages of easy controllable metering component, simple technology, low price, 200-700 deg.C reaction temperature, short manufacture period, saving energy resources. The prepared product has good nonlinear optical performance, can observe absorption peak in given wave length, separate from optical switch, optical computer, light wave.

Description

technical field [0001] The invention belongs to the composite field of nano-metal particles and inorganic non-metallic materials, and in particular provides a nano-gold (Au) particle-dispersed nickel oxide (NiO) optical film and a preparation method thereof, and relates to a nano-gold particle-dispersed nickel oxide nonlinear optical film material Composition design and preparation process. Background technique [0002] As a new type of functional material, nanoparticle / dielectric composite film has broad application prospects in the fields of catalysts, electricity, optics, magnetism, etc., especially nanometer metal particle dispersed oxide films have excellent nonlinear optical properties, and have been widely used in recent years. It has attracted great attention from scholars at home and abroad. Nano metal particle dispersed oxide film, due to the quantum size effect and surface effect of metal nanoparticles is very significant, surface plasmon resonance occurs under t...
