Both the decrease in the band gap and the appearance of absorption edges above 400 nm, which redound in a significant absorption of visible light, are accomplished by simply incorporating in situ different amounts of a typical chelating bidentate ligand, 1,10-phenanthroline, during the synthesis of these ceria nanocubes. Such a remarkable effect has been tentatively connected with the ability of this nitrogen-containing heterocyclic compound to coordinate Ce3+ cations from the ceria precursor salt, thus yielding intermediate N 2p states along the band gap of the oxide.
