摘要：

Electron-energy-loss spectroscopy has been used to investigate the changes of the electronic structure in Y1-xPrxBa2Cu3O7 (0x 1). The O 1s absorption edges and the low-energy-loss function indicate that Pr does not fill holes in the CuO2 planes. This suggests, by comparison with other experiments, that Pr localizes mobile holes thereby leading to the suppression of superconductivity and the metal-insulator transition. © 1990 The American Physical Society.
