Abstract

Fluorescence quenching microscopy (FQM) is demonstrated as a low-cost and high-throughput technique for seeing graphene-like 2D sheets such as MoS ₂. FQM provides high contrast and layer resolution comparable to those of scanning electron microscopy, but allows the imaging of samples deposited on arbitrary substrates, including non-conductive substrates such as quartz. Solution fluorescence quenching studies suggest that FQM should be feasible for many other 2D materials such as WS₂, Bi ₂Te₃, MoSe₂, NbSe₂, and TaS ₂.
