摘　　要：Silver-based quantum dots(QDs)such as Ag2S,Ag2Se,and Ag2Te,which emit in the second near-infrared window(NIR-II,900–1700 nm),have attracted great research interest due to their prominent optical properties and eco-friendly compositions.Over the past decade,the controllable synthesis,bandgap modulation,and fluorescence improvement of NIR-II Ag-based QDs have greatly promoted their practical applications.In this review,we summarize the development process and latest achievements of NIR-II Ag-based QDs,covering major synthesis techniques for fabricating NIR-II Ag-based QDs,general methods for improving their fluorescence properties and recent advances in the applications of NIR-II Ag-based QDs from bioimaging to optoelectronic devices.Finally,we discuss the challenges and prospects of NIR-II Ag-based QDs in their optical properties and applications.This review aims to present synthesis and modification strategies and future application prospects for NIR-II Ag-based QDs,providing guidance for the design and integration of fluorescent probes in NIR-II window.
