The calculations of the doped XXX in this work were carried out with the same structure of pure XXX crystal. This is probably not the case in real materials. The effects of structure relaxation after doping should be elaborated, which might have significant influence on the electronic structures. Meanwhile, the authors should also show whether this kind of doping is physically possible. In case, if this structure is not stable, all the calculations make no sense.

Another serious concern I have about this paper is the ``energy scissors approximation'' adopted in the calculation of the optical absorption. The parameter 2.0 eV is chosen to fit the experimental absorption edge. Then the optical band gap is determined from the absorption spectrum. My concern is that, in presence of the artificially shifted bands, what value the results have in this approximation.
