Abstract
Transition metal dichalcogenides (TMDs) are direct bandgap semiconductors [1], and they exhibit fascinating optical properties, such as valley polarization, room temperature excitons, and high optical nonlinearity. Single and few-layer TMDs and TMD-nanoparticles exhibit much stronger photoluminescence than the bulk material [2]. This property makes them an attractive candidate for use as mesoscale fluorescent markers, e.g., for use in fluorescence microscopy. As opposed to conventional fluorescent markers, such as fluorescent molecules they do not exhibit phototoxicity and have been shown to be biocompatible in contrast to, e.g., many types of quantum dots.
