Abstract
Photoluminescence properties are studied on scandia-stabilized zirconia for 8, 11 and 12 mol%-scandia-doped samples. Temperature dependence of multiple sub-bands observed under irradiation of He-Cd laser light (3.81 eV) is investigated and shows a clear contrast between 11 and 12 mol%-doped samples. A model is presented, which explains by thermal properties for both ground and excited electronic states of oxygen vacancies under photo-excitation.
