Giant change of MoS2 optical properties along amorphous–crystalline transition: broadband spectroscopic study including the NIR therapeutic window

The annealing of MoS 2 films shows a transition from the mixed 1T′@2H local order (amorphous) toward the long-range 2H order (polycrystalline). So far uncovered potential of amorphous MoS 2 as an agent for photothermal therapy is evidenced.
