| 英文摘要 | In this work, we investigated the doping effect on the local structure of Co, Zn, and O in Zn1-xCoxO (x = 0.02 and 0.2) nanocrystals by X-ray absorption spectroscopy combined with A initio calculations. We identified the presence of a distorted CoO4 structure and showed that the distortion propagates homogeneously in the matrix with increasing doping concentration. The presence of a distorted matrix lattice plays an important role in the mechanism of room-temperature ferromagnetism observed in diluted magnetic semiconductor materials, which is in agreement with a new mechanism recently introduced. Information on the electronic structure of the bottom of the conduction band has been achieved by O K-edge X-ray absorption near-edge spectroscopy that also addresses significant contributions of the matrix lattice distortion on the distribution of O 2p states. |
