The effect of surrounding solvents on the photoluminescence (PL) of MoS 2 monolayers on Si/SiO 2 substrates is studied. A redshift (up to −60 meV) is observed for MoS 2 monolayers with nonhalogenated solvent surroundings. A blueshift (up to 60 meV) and intensity increase (2–50 times) are observed for monolayers with halogenated solvent surroundings.
