Structural and optical properties of graphene with a vacancy and B, N, O and F doped graphene have been investigated computationally using density functional theory (DFT). We find that B is p-type and N, O and F doped graphene layers and graphene with a vacancy are n-type semiconductor. Optical properties for both cases of in plane (E⊥c) and out of plane (E‖c) polarization of light are investigated; and observed that with the increase in the number of electrons entering the supercell, the amount of absorption of the system decreases and the absorption peaks are transferred to more energies (blue shift).
