Electronic and Structural Properties of Oxides

Photoluminescence excitation and quenching spectroscopy techniques were applied to the red band, and the 1.68, 1.945 and 2.156 eV lines in chemical vapour deposition diamond films. Ground state positions for the 1.68, 1.945 and 2.156 eV centers are found as EC −2.1, −2.0 and −2.8 eV, respectively. Interpretation of the 1.945 and 2.156 eV centers as [N-V]− and [N-V]0 defect states is supported.
