  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.
