Abstract

The invention relates to a nonlinear optical film with gold silver nanoparticles and dispersal oxide and its preparation method, which belongs to the metal nanoparticles and oxide composite material field. The nonlinear optical film with gold silver nanoparticles and dispersal oxide is characterized in that the a composition general formula of the chemical component is AgxAuy / (Co3O4)1-x-y, wherein x,y is respectively expressed the mol fraction of the composition element of Ag and Au, the value range of x is 0.01-0.60, the value range of y is 0.01-0.60, the value range of 1-x-y is 0.20-0.98. The gold silver nanoparticles are dispersed in a cobaltosic oxide matrix in a form of alloy, the diameter range of the gold silver nanoparticles is 1-500nm. The peak position of an alloy absorption peak is regulated and controlled by the mol fraction of gold silver composition elements. The absorption peak is appeared at the wave band of 350-650nm of the film, the film has excellent nonlinear optical property and increases the wavelength selection scope of non-linear luminous absorption.

Description

technical field [0001] The invention belongs to the field of composite materials of metal nanoparticles and oxides, and in particular proposes a gold-silver alloy nanoparticle-dispersed oxide nonlinear optical film and a preparation method thereof, and relates to the design and operation of various metal nanoparticle-dispersed oxide optical films. Preparation Process. Background technique [0002] With the outbreak of energy crisis worldwide and the emergence of environmental degradation issues, energy and environment have become two major issues that human beings face and need to be solved urgently in the 21st century. Heterogeneous photocatalysis has unique properties such as deep reaction at room temperature and direct use of solar energy as a light source to drive the reaction. As an ideal environmental pollution control technology and clean energy production technology, it has attracted increasing attention. In recent decades, the research on metal nanoparticle nonline...
