Abstract The photoelectric properties of pristine, Mn-doped, Fe-doped and Co-doped graphene are investigated by DFT investigation. Doped graphene exhibits interesting tuning of electronic and optical properties. The gap value of Mn-doped graphene is the largest, 0.312 eV, then Fe-doped graphene, 0.214 eV, and Co-doped graphene, 0.070 eV. The absorption peaks of doped graphene become weak, especially the peaks of Mn-doped graphene. The optical absorption edge of doped graphene have a clear blue-shift to a higher energy region. Besides, the peaks of energy loss function are much lower, indicating that the introduction of metal atoms reduces the excitation energy of the plasma.
