Recent advances in lanthanide-based MOFs for luminescence detection

Abstract

Lanthanide-based metal–organic frameworks (Ln-MOFs) have been well developed in recent years because of their unique optical properties, including long luminescence lifetimes, sharp emission peaks, large Stokes shifts, and tunable luminescence colors, which enable them to be used for high-performance luminescence-based detection. In order to gain a comprehensive understanding of luminescence sensing, this paper reviews how Ln-MOFs offer highly sensitive and selective detection in areas such as environmental monitoring, biomedicine, food safety, and public security. In addition, this paper addresses the luminescence sensing processes and recent advances in Ln-MOFs. It also discusses the design strategies and provides a forward-looking view on potential prospects and challenges.
