A shift of the photoluminescence (PL) emission was observed in ZnS prepared by microwave assisted
solvothermal method with the increase of the time in microwave. In this work we reported a study of the optical behavior
linking with the structural disorder according to XRD and FEG-TEM results. The reduction of intrinsic defects in the
lattice is responsible for the decrease of electronic levels in the band gap changing the PL profile. This effect was
confirmed by electronic structure calculations.
