Raman Spectroscopy Study of YSZ Co-Doped with CeO₂/Gd₂O₃

Abstract:

Phase characterization is critical in material properties probing. In this study, Raman scattering was employed to identify the phase of YSZ co-doped with CeO₂/Gd₂O₃. As a comparing, XRD for co-doped YSZ was also measured. The results show that introducing a small amount of CeO₂/Gd₂O₃ into YSZ can lead to a change on Raman spectroscopy. Raman peaks appear with co-doping is attributed to the local structure change which caused by the re-distribution of vacancy. Comparing to XRD, Raman spectroscopy shows a more sensitive on the phase identify for the YSZ with a small amount dopant.
