Controllable bandgap widening from 1.8 to 2.6 eV is reported from oxidized MoS 2 sheets that are composed of quilted phases of various MoS x O y flakes. The exfoliated flakes have large size (≥100 μm × 100 μm) sheets with average thickness of 1.7 nm. Remarkably, fine reversible tuning of the bandgap is achieved by postprocessing sulfurization of the MoS x O y sheets.
