| 英文摘要 | The fast neutron with the energy of 0.1 similar to 500 mev and the dose with 1.0x10(18) neutron/cm(2) was chosen to irradiate alpha-al2o3 single crystal. the formation of defects and the change of optical property were studied by absorption and luminescence spectra. the results showed that alpha-al2o3 single crystal was colored up by the irradiation of neutron and there were absorption peaks at 206, 228 and 256 nm, etc. there were also luminescence peaks at 326; 331 and 379 nm, etc. it was founded that there were many color centers, such as f+, f-2, f-3(+) color centers, in alpha-al2o3 single crystal after neutron irradiation. the study indicated that the color center was due to the origin of oxygen vacancy. the concentration n of color centers were calculated. the result of pat indicated that there were vacancies in alpha-al2o3 single crystal after neutron irradiation and the increase of single-vacancy was greater than that of multiple-vacancy. |
