Study on the electronic structures and the optical properties of the Mg-doped LiBaF sub(3) crystal
The most possible substituting positions of impurity magnesium ions in LiBaF sub(3) crystal are studied using the general utility lattice program (GULP). The electronic structures of Mg-doped LiBaF sub(3) crystal are studied within the framework of the fully relativistic self-consistent Dirac-Slater...

| description | The most possible substituting positions of impurity magnesium ions in LiBaF sub(3) crystal are studied using the general utility lattice program (GULP). The electronic structures of Mg-doped LiBaF sub(3) crystal are studied within the framework of the fully relativistic self-consistent Dirac-Slater theory using DV-X alpha software. It is predicted that the most possible defect model is the [MathML equation] in the Mg: LiBaF sub(3) crystal, which exhibits donor level in the forbidden band. The optical transition energy from the Mg 3s state to the Ba 5d state is 2.975 eV, which is very close to the experimental result. It is indicated that the 420 nm absorption band originates from [MathML equation] and the presence of the 510 nm luminescence band is related to the defect cluster [MathML equation] in the Mg:LiBaF sub(3) crystal too. |
