Abstract
Measurements of the absorption coefficient on the fundamental optical absorption edge of α-ZrO2 show that an indirect interband transition at 4.70 eV precedes two previously reported direct transitions. This result is in agreement with recent theoretical calculations of the α-ZrO2 band structure.Keywords
