Fluorescence Quenching: Seeing Two‐Dimensional Sheets on Arbitrary Substrates by Fluorescence Quenching Microscopy (Small 19/2013)

Fluorescence quenching microscopy (FQM), an optical technique originally developed for imaging graphenebased sheets on arbitrary substrates is extended by J. Huang and co-workers on page 3253 to other two-dimensional materials, such as molybdenum disulfide (MoS2) sheets (background image). The panels in the main image are the MoS2 flakes imaged by reflectance mode optical microscopy (left), FQM (middle), and scanning electron microscopy (right).
