Detector has become an indispensable part of human beings.The increasing demand for photodetectors with high performance has promoted the research of novel materials.At the same time,with the development of rising material system,two-dimensional(2D)materials attract a lot of attention,while the suitable option for fabricating photodetector is still limited.The prospering of bismuth chalcogenides injected new vitality for material field,thereinto,the unique topological insulator characteristics make the research on bismuth selenide(Bi2Se3)and bis-muth telluride(Bi2Te3)intriguing.2D Bi2X3 also exhibits unique features among various 2D materials,of which,the adjustable narrow energy band gap and polarization-sensitive photocurrent contribute to the promising appli-cation of high performance and broadband photodetector.In this review,from a bottom-up perspective,we summa-rize fundamental properties,synthesis method,photode-tector performance of 2D Bi2X3 based on the previous study,which provide an overall perspective of 2D Bi2X3.Wherein,the section of the photodetector is specifically discussed with regard to pure Bi2X3 photodetector and heterojunction photodetector.A brief summary and outlook were also explored in the end.
