Abstract
A new 1,3‐diketonato ligand containing both an electron‐donor [4‐(dimethylamino)benzene] and an electron‐acceptor (4‐nitrobenzene) group and its lanthanide complexes have been prepared. They display an intense intra‐ligand charge‐transfer absorption transition in the visible region of the spectrum at 400–550 nm which was utilized to achieve visible‐light excitation of metal‐centred infrared luminescence of Nd^III^, Er^III^ and Yb^III^ ions.
