Abstract
The invention concerns an optoelectronic device () comprising: a substrate (); a first layer () covering the substrate, the first layer having a thickness greater than or equal to 15 nm and comprising a first material having an extinction coefficient greater than or equal to 3 for any wavelength between 380 and 650 nm; a second layer () covering and in contact with the first layer, the second layer having a thickness less than or equal to 20 nm and comprising a second material having a refraction index of between 1 and 3 and an extinction coefficient less than or equal to 1.5 or any wavelength between 380 and 650 nm; and conical or frustoconical wire semiconductor elements () each having a light-emitting diode stack (DEL), being in contact with the second layer.
