摘要：

The authors report ellipsometric spectra of YBa//2Cu//3O//7 measured on ceramic, thin film, and single crystal samples. Absorption bands centered at 2. 8, 4. 1, and 4. 7 eV are observed in all three types of samples. The spectra change only slightly upon cooling from room temperature to 7 K. The spectral structures are assigned to interband transitions involving O(2p)-Cu(3d) and O(2p)-Ba(5d) bands.
