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 WS 2 , Bi 2 Te 3 , MoSe 2 , NbSe 2 , and TaS 2 .
