Ag+-sensitized lanthanide luminescence in Ln3+ post-functionalized metal–organic frameworks and Ag+ sensing

Abstract

The weak fluorescence of Ln³⁺-doped (Ln = Sm, Dy, Nd, Yb, Er) metal–organic frameworks (MOFs) was greatly enhanced by Ag⁺. Single-phase white-light emitters based on the resulting 4d–4f heterometallic co-doped MOFs could be realized. Furthermore, the Sm³⁺-doped MOF has been used for highly sensitive sensing of Ag⁺.
