Helium ion irradiation effects on neodymium and cerium co-doped Gd2Zr2O7 pyrochlore ceramic

Raman spectra obtained from Nd2Ce2O7 compositions before and after irradiation at various fluences from 1 × 1015 to 1 × 1017 ions/cm2. The Nd2Ce2O7 matrix keeps fluorite phase before and after irradiation at various fluences from 1 × 1015 to 1 × 1017 ions/cm2, which present good irradiation tolerance.196
