We have employed tight-binding quantum chemistry method involving a new calculation method for rare earth elements to calculate the electronic structure of BaMgAI10O17:Eu2+ (BAM). The new method considers the particular nature of the 4f orbitals which is specified by their location respect the nuclei and their degeneration properties. Our calculation results indicate that the oxygen vacancy in BAM cause the red-shift of luminescence color and the degradation of brightness.
