4f → 3d sensitization: a luminescent Eu^II–Mn^II heteronuclear complex with a near-unity quantum yield

Abstract

A new heteronuclear EuII–MnII complex with high photoluminescence quantum yield is designed and synthesized, which represents the first example of f → d molecular sensitization.

Excited-State Dopant–Host Energy-Level Alignment: Toward a Better Understanding of the Photoluminescence Behaviors of Doped Phosphors

“…In the past decade, a large number of metal halide phosphors, mostly hybrid organic–inorganic materials, have emerged, primarily due to their structural and compositional richnesses, as well as their facile and low-cost synthesis. Not surprisingly, these compounds have shown various PL behaviors, as observed in numerous reports. − …”
