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.
