Abstract

Gd-doped ceria (GDC) films were synthesized on Si substrates from (Ce, Gd)-EDTA solutions and atmospheric sintering. The (Ce, Gd)-EDTA solutions were coated onto silicon by a commercial spin coater and the coated samples were sintered in a furnace at 850^oC for 1 h. For the composition of Ce: Gd=0.8:0.2 in the EDTA complex with sintering at 850^oC only the crystalline phases of Ce_0.8Gd_0.2O_1.9 were synthesised on the Si substrates. Microstructures of the Ce_0.8Gd_0.2O_1.9 films had 78 3D-relative densities as revealed by ellipsometry. Furthermore, the oxidation degree of the Ce ion was equal in the obtained Ce_0.8Gd_0.2Ofilms at various experimental conditions as confirmed by XPS analysis.

Keywords
