Application of organic–graphene hybrids in high performance photodetectors

Abstract

High performance photodetectors play important roles in the improvement of innovative technologies in many fields, for instance, medicine, military, optical communication, environment monitoring, etc. Graphene functionalized with photo-active units has been investigated intensively due to the unique optical and electronic properties of the graphene material, which remarkably sustains and expands the graphene boom. This review focuses on the research progress in applications of organic–graphene hybrid films in photodetectors. We discuss the sensitization mechanisms of photo-response, fabrication of hybrid material devices and sensitization of graphene by different organic molecules. The organic–graphene hybrid materials hold great promise to realize high performance photodetectors with high responsivity and a fast response.
