摘要：

We have measured the room temperature reflectivity spectra in the range 500-25000 cm-1 on YBa2Cu3O6+x (0 < x < 1) and Nd1+yBa2-yCu3O6+x (0 < y < 0.5) polished ceramics as a function of doping (x and y). In the metallic range, in both systems, the Drude contribution and the mid-infrared band exhibit a correlated increase with hole doping level (x or y). The conductivity is compared to recent simulations of the t-J model as a function of hole doping.
