▎ 摘　　要

Graphene has been widely investigated and applied in almost all areas of science and technology. Modulation of graphene properties is needed for its potential utilization in various applications. Chemical doping is one of the most attractive and efficient strategies to alter graphene properties. To date, substantial progress in this area has been reported, which needs to be thoroughly reviewed for its effective implementation in the development of commercial products in the days to come. This article presents a systematic, critical, and more informative review of the recent advancement in the chemical doping of graphene and its applications. Starting with a brief history along with the properties and synthesis of graphene, different experimental approaches to chemical doping and their outcomes reported so far are systematically documented. Further, extensive studies based on potential applications of doped graphene in various fields including light-emitting diodes, photodetectors, solar cells, energy storage devices, sensors, and medical diagnoses are discussed and presented. Finally, the study is concluded with discussions on future prospective research work in this area.
