Abstract

It was found for the first time that the electrical conductivity of Y-substituted Cd₂Sb₂O₇, Cd_2(1–x)Y_2xSb₂O₇, with the pyrochlore structure, is larger than at least 3.3 × 10° Scm^–1 and the optical band gap of the sample is wider than 3.5 eV. These values indicate that Cd_2(1–x)Y_2xSb₂O₇ pyrochlore has a characteristic of a transparent conductor.
