Twilight fluorescence (TwiF) microscopy is capable of imaging a single layer graphene compound floating in a solution. In this study, a simplified theory of dark TwiF contrast is developed and verified experimentally. TwiF allows not only observing morphology and movements of individual graphene but also evaluating a number of layers and optical properties of a floating graphene sheet in real time.
