| 摘要 | Extended X-ray absorption spectroscopy (EXAFS) was used to determine the local structure of luminescence centres in Eu3+ doped, Eu-Bi doped, Eu-Tb doped nanoscale yttrium oxide as well as Eu3+ doped nanoscale yttrium Silicate. It was shown that the Eu-O bond distance of the first coordination shell has an important effect on emission intensity, and the doping of Bi and Tb changes the Eu ion coordination environment, which results in the change of emission intensity. This result can be explained by the configurational-coordinate model. |
