摘要: 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 n3 of which is lower than that of the refractive index n0 of 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.

摘要: A photopolymerizable composition comprises at least a polymerizable resin, a photosensitizer, an annihilator, and a photoinitiator. The photosensitizer is formulated to absorb an excitation light signal received in a first range of wavelengths. The annihilator is formulated to emit a light signal in a second range of wavelengths different from the first. During the absorption of light by the photosensitizer in the first range of wavelengths, the annihilator emits a light signal in the second range, a photon energy of the emitted light signal being greater than a photon energy of the light signal received by the photosensitizer. The annihilator is also formulated to implement an energy transfer mechanism to excite the photoinitiator for polymerization of the resin. The excited photoinitiator is formulated to generate at least one polymerizable initiator to cause the polymerization reaction. Related methods, such as three-dimensional printing methods, and materials are also disclosed.
