摘要：

We prepared two types of nanocomposites by the co-sputtering method: (a) Si-dispersed in SiO2 Al2O3 or MgO, and (b) MOX/SiO2, MOX/Al2O3 (M: transition metal from Ti to Zn). The nanostructures and the chemical states of nanocomposite constituents were characterized by TEM and XPS, respectively. The relationship between the optical properties and the nanostructures were also studied. For Si-dispersed nanocomposites, photoluminescence increased during the disproportionation process of SiOX. Quantitative analysis of nanocomposite series, MOX/SiO2 and MOX/Al2O3 revealed that the concentration of dispersoid did not always agree with simple estimations from the sputtering yield and the area ratio.
