AB  - A series of Ce1-xBaxO2-y (5 LT = x LT = 0.20) nanometric powders were synthesized by self-propagating room temperature synthesis. XRD and Raman scattering measurements were used to characterize the samples. at room temperature. All the samples are solid solutions with fluorite type structure with an average crystallite size about 5 nm. The redshift and asymmetric broadening of the Raman F g mode can be well explained with combined confinement and strain effects because of the nanocrystalline powders nature. The appearance of the additional peaks at similar to 560 cm(-1) and similar to 600 cm(-1), are attributed to extrinsic and intrinsic O2- vacancies in ceria lattice. Raman spectra of temperature treated Ce0.80Ba0.20O2-delta sample revealed the instability of this system.
