On the basis of one-electron Hartree-Fock approximation , the extended-ion method and ab initio method have been used to investigate the F center migration between F~- layers, Br~-layers and from F~- layer to Br~- layer .
本文是在单电子Hartree-Fock近似的基础上采用扩展离子方法和全电子从头计算方法,研究了BaFBr:Eu~(2+)晶格中的F~-离子层间的F心迁移,Br~-层的F心迁移和F~-离子与Br~-离子层间F心迁移过程中的能量势垒和F心基态、激发态以及激子能量,对于F心和激子的研究结果与实验符合的很好。
