Abstract: A process of growth in the thickness of at least one facet of a colloidal inorganic sheet. By sheet is meant a structure having at least one dimension, the thickness, of nanometric size and lateral dimensions great compared to the thickness, typically more than 5 times the thickness. By homostructured is meant a material of homogeneous composition in the thickness and by heterostructured is meant a material of heterogeneous composition in the thickness. The process allows the deposition of at least one monolayer of atoms on at least one inorganic colloidal sheet, this monolayer being constituted of atoms of the type of those contained or not in the sheet. Homostructured and heterostructured materials resulting from such process as well as the applications of the materials are also described.

Abstract: A device that emits light in response to an electrical or optical excitation, such as LEDs, displays, e-readers, device includes at least one anisotropic flat colloidal semiconductor nanocrystal whose smallest dimension, namely the thickness, is smaller than the other two by a factor of at least 1.5, the emitted light having an intensity and a polarization that vary according to the angle formed by the light emitting direction and the normal to the largest surface of the flat nanocrystal. The device allows to realize a light-emitting device exhibiting simultaneously a high emission spectral finesse and allows proper control of the wavelength, the directivity and/or polarization of the emitted light, and thus increases the brightness and color gamut of displays composed of such a device. Such devices are found for example in displays, televisions, mobile phones, tablets, or computers. The various embodiments of these devices are also presented.
