Abstract

Selection of the excitation wavelength at nonresonant and resonant Raman conditions provided detection selectivity in the tetragonal and cubic phases in CeO2-ZrO2 nanocrystals, respectively. It was suggested that cubic-phase domains containing Ce3+ deficiencies were involved in the tetragonal-phase matrix.
