Abstract
A contrast-amplifying carrier for observing a sample, includes a transparent substrate bearing at least one absorbent coating suitable for behaving as an antireflection coating when it is illuminated at normal incidence at an illumination wavelength λ through the substrate and when the face of the coating opposite the substrate is in contact with a medium referred to as a transparent ambient medium, the refractive index nof which is lower than that of the refractive index nof the substrate. The absorbent coating comprises: an absorbent sublayer referred to as the contrast sublayer, deposited on the surface of the transparent substrate; and an absorbent layer referred to as the sensitive layer, distinct from the contrast sublayer and comprising between 1 and 5 sheets of a graphene-type material. Methods for producing and for using such a contrast-amplifying carrier are also provided.
