摘　　要：石墨烯量子点(GQD)是碳量子点的一种,不仅具有碳量子点的优良性质,还具有其他量子点无法比拟的光学特性。概括了石墨烯量子点光学非线性原理特点,由于其二阶或三阶非线性电极化强度决定非线性光学的特性,并且其表面导电性呈各向同性,选择一种更加合理的方法来描述其光学非线性,由此论述得到其三阶电流的表现形式。随后,详细阐述了国内外对在光电领域、生物光子领域和催化领域中GQD的研究成果,简要分析了其性能参数、作用特点、潜在能力等,指出了GQD目前面临的关键技术问题,并对此从制备方案设计和优化作用机制等方面阐述了技术解决途径,最后对未来GQD的应用前景进行了展望。The graphene quantum dot(GQD)is one type of carbon quantum dots,and has the excellent properties of carbon quantum dots and optical properties unmatched by other quantum dots.The characteristics of the optical nonlinear principle of the GQD are comprehensively summarized.The second-or third-order nonlinear electric polarization strength determines the characteristics of nonlinear optics which is described by a more reasonable method,and the surface conductivity of the GQD is isotropic,thus the expression of its third-order current is achieved.Then the research results of the GQD in the field of optoelectronics,biophotonics and catalysis are elaborated in detail.The performance parameters,function characteristics and potential capabilities of the GQD are briefly analyzed,and the key technical problems faced by GQDs are pointed out.The technical solutions are expounded in the aspects of the preparation scheme design and the optimization of the action mechanism.Finally,the application prospect of future GQDs is forecast.
