摘要：

The room-temperature radiative properties of YBa2Cu3O7-delta superconducting films with varying oxygen content (delta = 0 to 1) on a LaAlO3 substrate are investigated. The fitting of reflectance spectra using thin-film optics and the Drude-Lorentz model function with multiple oscillators determines the optical constants. The film with high oxygen content (delta = 0) has a metallic optical behavior. A decrease in the oxygen content causes a removal of free carriers, and the film with low oxygen content (delta = 1) acts like a dielectric with a very weak free-electron contribution. Knowledge of the optical constants of oxygen-deficient YBa2Cu3O7-delta films facilitates accurate substrate temperature measurement and control during the film deposition process.
