Abstract
The invention relates in particular, to the area of devices or systems whose optical operation is modified by changing the optical properties of the medium of which they are formed and that are intended, in particular, for limiting the luminous intensity transmitted by the system. Specifically, the invention relates to a device for selectively limiting the intensity of a radiation, including a liquid or solid medium containing nanotubes, for example, nanotubes made of carbon or boron, tungsten, silicon, or composite nanostructures, such as BN, BC3, BC2N, CN(C3N4), or MoS2.
