We have performed the state-of-the-art calculations within the framework of density functional theory (DFT) for N and F co-doped ZnO with the aim to tune the energy band gap that may be useful for opto-electronic devices. The hybrid functional have been adapted to explore the properties of pristine and N, F co-doped ZnO. By configurational ensembles and statistical mechanics, we are presenting site disorder solid. The estimated probability for N and F co-doped ZnO decreases with increase of temperature indicates disorderness in considered system. We obtain impurity band above the valence band maxima (VBM) at Gamma-point that mainly derived by N-2p orbitals. The absorption coefficient (alpha) has been calculated, shows red shift with increasing concentration (x).
