| 中文摘要 | The optical absorption and EPR spectra of Ni2+-VAg centres in the AgCl:Ni2+ and AgBr:Ni2+ systems have been investigated theoretically on the basis of the complete energy matrices including the electron-electron repulsion interaction, the ligand field interaction, the spin-orbit coupling interaction, and Zeeman interaction. Because the charge compensation forms a silver ion vacancy (VAg) which makes the attractive force acted on the each ligand ion different, it was determined that the Ni-X (X = Cl, Br) distance next to VAg is shorter than others for both AgCl:Ni2+ and AgBr:Ni2+ systems in the tetragonal symmetry. Besides, it was found that the local lattice structure of (NiX6)4- clusters in AgCl and AgBr crystals exhibit a compression distortion. This compression distortion may be ascribed to the fact that the Ni2+ ion has a smaller ionic radius and more effective charge than the Ag+ ion. |
