Abstract

The authors use SIMS measurements to examine the composition of a Pr 0.1Ce0.9O2-δ thin film following an oxygen surface exchange measurement via optical absorption relaxation. A significant concentration of impurities (Si, K, Na, and Ca) were observed to accumulate on the film surface, with a concentration profile extending approximately 60 nm into the film, following the high temperature measurements. This resulted in a significant decrease in the oxygen exchange coefficient, kex. Potential sources for the impurities are discussed.
