摘要：

The spectral dependence of the photoconductivity in polycrystalline diamond films has been studied between 0.5 and 2.5 eV. Several structures are observed (a threshold at 0.85 eV, peaks at 1.1 and 1.4 eV, a broad band at 1.9 eV and weak peak at 2.4 eV), indicative of the presence of deep levels in these films. The peak at 1.1 eV is ascribed to the photoionization of acceptor states located at about 1 eV above the valence band with some evidence of electron-phonon interaction at the sites.
