抄録

Photoluminescence (PL) and electron-spin-resonance (ESR) studies were carried out on thermal SiO 2 films after B + or P + implantation. Two PL bands at 4.3 eV and 2.6 eV were observed. For the 4.3-eV bands, two PL excitation bands were observed at 5.0 eV and 7.4 eV. Based on the comparison with those observed in oxygen-deficient-type bulk SiO 2, the 4.3 eV and 2.6 eV PL bands are ascribed to oxygen vacancies induced by ion implantation. The decay of the 4.3-eV band in ion-implanted thermal SiO 2 films follows a power low or stretched exponential, suggesting the distribution of PL lifetime. The ESR signal of the paramagnetic E′ centers in ion-implanted thermal SiO 2 films were found to be broadened by dipole-dipole interactions between the closely spaced defects. The PL and ESR results suggest that the oxygen vacancies induced by ion implantation in thermal SiO 2 films are perturbed by the local network structures.
