| Abstract Scope |
Cerium dioxide (CeO2) has been given much attention in material science due to its wide array of applications from solid oxide fuel surrogates to biomedical devices. In the present work, we report the impact on the photoluminescence due to concentration for trivalent Europium doped Ceria. Europium has a similar ionic radius as cerium which can easily be doped into the ceria host lattice. Using the photoluminescent properties as a probe into the microstructure, we can gain more information than conventional techniques and in a nondestructive way. As an increase in doped lattice sites, the asymmetric ratio and peak broadening was observed as a function of the dopant concentration under normal conditions. It is our hope that this work can help to enhance the framework of future predictive models for surrogate use. |
