Description

technical field [0001] The invention belongs to the field of composite nonlinear optical materials, in particular to a naphthalocyanine-aminated graphene oxide composite nonlinear optical material and a preparation method thereof. Background technique [0002] With the development of optical research, especially the gradual maturity of laser technology, materials with excellent nonlinear optical properties have become one of the hot spots of scientific research. Graphene oxide (GO) has good application prospects in the field of nonlinear optics due to its excellent nonlinear optical properties, but its poor solubility limits its application in popular fields. Therefore, the improvement of the properties of graphene oxide by introducing water-soluble groups is the focus and focus of current research. [0003] Among the functional groups contained in the surface layer of graphene oxide, less electron-donating groups are contained, which limits its important role in the electr...
