摘要：

Using rotating-analyzer ellipsometry we have measured the dielectric function of quenched YBa2Cu3O7-delta samples (with intermediate oxygen content) as a function of the time-tau the samples spent in laboratory atmosphere. We find an increasing concentration of Cu(I)+ ions with tau, in accordance with previous explanations of the rise of T(c) with tau.
