Dramatic band gap reduction incurred by dopant coordination rearrangement in Co-doped nanocrystals of CeO(2)
A dramatic band gap narrowing of 1.61 eV has been observed in Co-doped nanocrystals of CeO(2) (ceria), as a result of thermal annealing, without changing the ceria crystal structure and the Co concentration. As demonstrated by x-ray absorption fine structures, thermal annealing incurs an oxygen coor...
