Abstract
An optoelectronic device including light-emitting diodes (LED), each light-emitting diode including a semiconductor element corresponding to a nanowire, a microwire, and/or a nanometer- or micrometer-range pyramidal structure, and a shell at least partially covering the semiconductor element and adapted to emit a radiation and for each light-emitting diode, a photoluminescent coating including a single quantum well, multiple quantum wells or an heterostructure, covering at least part of the shell and in contact with the shell or with the semiconductor element and adapted to convert by optical pumping the radiation emitted by the shell into another radiation.
