Article Synopsis
- CeO samples were made using the polymeric precursor method with varying calcination temperatures, leading to changes in particle size and shape.
- Advanced techniques like positron annihilation lifetime spectroscopy (PALS) and electron paramagnetic resonance (EPR) revealed the presence of different types of oxygen vacancies associated with various cerium ions.
- Impedance spectroscopy showed that as the calcination temperature increased, there was a reduction in electrical conductance and the formation of polarons in the material.
