NOVELTY - Making a three-dimensional graphene oxide microstructure, comprises: adding a photoreactive agent into a graphene oxide solution, where the photoreactive agent is a photoactivator in an nonlinear optical method; activating the photoactivator in the graphene oxide solution by a beam emitting from an excitation module to produce a singlet oxygen with high activity; and activating a graphene oxide by the singlet oxygen for an unpaired electron of the graphene oxide covalently bonding with another graphene oxide to form a three-dimensional graphene oxide microstructure. USE - The method is useful for making a three-dimensional graphene oxide microstructure, which is useful in: the development of all electronic and optical components e.g. optical amplifier, field-effect transistor and wavelength shifter; biocompatible materials, proteins or organic framework to form a microfluidic biochip or precursor of disease; and to form optical material via three-dimensional mode for creating ultrashort pulse, for application in photoelectric industry and biomedical industry. ADVANTAGE - The method: utilizes the multiphoton excitation of nonlinear optical technique of ultrafast laser system that exhibits improved efficiency of two-photon crosslinking and allows the two-dimensional graphene oxides to be efficiently crosslinked, thus preventing the thermal damage; efficiently improves the problem that hexagonal carbon structure of the traditional graphene cannot be formed three-dimensional type and efficiently remedy the defects of the traditional graphene for making any free form of the three-dimensional graphene oxide microstructure; utilizes unique characteristics of the graphene like special bandgap, electric charge and ultrasmall resistance to make any photoelectric element for expanding the development of three-dimensional composites and accelerating the development of high-speed transistor or super capacitor by reducing the size of the traditional electric elements and accelerating the development of superconductive industry; and utilizes femtosecond laser which instantly provides enough photon energy density in the focusing point to process the production of the any free form of three-dimensional microstructure of the graphene oxide, and the three-dimensional microstructure of the reduced graphene oxide is efficiently produced via tuning the laser power and the scan rate of the femtosecond laser to achieve different levels of graphene oxide reduction and integrity of the structure.
