<br/>Due to their combination of long luminescence lifetimes and higher absorption cross-sections, heterobimetallic complexes containing lanthanides and transition metals are becoming increasingly suitable for applications in catalytic processes and bioimaging techniques, as well as offering the opportunity to study energy transfer processes between d and f orbitals. Non-radiative quenching of the excited states competes with luminescence. This competition may be optimally studied in a family of three-fold-symmetric complexes with phosphinoamide ligands, which provide stability for the lanthanide-transition metal center’s dative interaction and aid in its metal-to-metal charge transfer (MMCT). The first-row transition metals Fe, Co, and Ni are paired with lanthanides La, Eu, and Tb to investigate their metal-metal interactions via their quantum yields and luminescent lifetimes. The results are compared with monometallic complexes and free metal ions in solution.<br/>
