We addressed the frequency behavior of optical absorption of Boron Nitired in the presence of electronic interaction. The Hubbard model has been applied to find the excitation spectrum of compound within mean field approximation. Long rang antiferromagnetic ordering has been considered to obtain ‌optical absorption. Fermi golden rule under time dependent interaction potential between light and matter has been implemented to capture the relation for optical absorption. The results show the increase of coulomb interaction and sublattice magnetization factors leads to decrease energy gap in the optical absorption of Boron Nitired which has been implied via band insulator transition implication.
