摘要
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 .
