Abstract
In this paper, La2O3 doped with varied Ce3+ concentrations were synthesized via hydrothermal co-precipitation followed by high temperature calcined process in H-2/N-2 atmosphere. Three new peaks show up at 698, 650 and 558 in O-17 solid state NMR spectra due to Ce3+ doping. The intensies of these peaks increase with Ce3+ concentration. According to the resonant frequencies and the intensities, the peaks at around 698 and 650, and 558 are assigned to four-coordinated OCeLa3 and six-coordinated OCeLa5 species, respectively. The results show that O-17 solid-state NMR spectroscopy can be used to study rare earth doped oxides for applicable functional materials.
