Title: OPTOELECTRONIC DEVICE WITH LIGHT-EMITTING DIODES
Abstract:
The invention relates to an optoelectronic device (5) comprising light-emitting diodes (LED), each light-emitting diode comprising a semiconductor element (22) corresponding to a nanowire, a microwire, and/or a nanometer- or micrometer-range pyramidal structure, and a shell (24) at least partially covering the semiconductor element and adapted to emit a radiation and for each light-emitting diode, a photoluminescent coating (28R, 28G, 28B) comprising 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.
