Abstract

Abstract: Luminescent Janus nanoparticles refer to a special category of Janus‐based nanomaterials that not only exhibit dual‐asymmetric surface nature but also attractive optical properties. The introduction of luminescence has endowed conventional Janus nanoparticles with many alluring light‐responsive functionalities and broadens their applications in imaging, sensing, nanomotors, photo‐based therapy, etc. The past few decades have witnessed significant achievements in this field. This review first summarizes well‐established strategies to design and prepare luminescent Janus nanoparticles and then discusses optical properties of luminescent Janus nanoparticles based on downconversion and upconversion photoluminescence mechanisms. Various emerging applications of luminescent Janus nanoparticles are also introduced. Finally, opportunities and future challenges are highlighted with respect to the development of next‐generation luminescent Janus nanoparticles with diverse applications. Abstract : Luminescent Janus nanoparticles have attracted increasing attentions due to their asymmetric features and alluring optical properties. This review summarizes recent achievements in the field of luminescent Janus nanoparticles with a focus on the synthesis strategies, photoluminescence mechanism (i.e., downconversion and upconversion), and various applications including sensing, bioimaging, cancer therapy, etc.
