Abstract
We analyse infrared-visible-near-ultraviolet spectra of oxide material s in the semiconducting or metallic phase. We show that the response o f laser-ablated YBa2Cu3O7 film call be fitted by a modified Drude term without mid-infrared absorptions. Mid-infrared and visible absorption s are discussed for textured YBaCuO, BaBiO3 and Pr2NiO4+delta as well as indication of their polaronic origin.
