摘要

The weak fluorescence of Ln(3+)-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+.
