Abstract
(EN)
The invention relates to an optoelectronic device (100) comprising a light-emitting diode (101) configured to emit electromagnetic radiation according to an emission wavelength of the light-emitting diode (101) included in the ultraviolet. The optoelectronic device (100) comprises an optical device (102) configured to extract photons generated by the light-emitting diode (101), said optical device (102) being arranged on an emission face (103) of the light-emitting diode (101), said optical device (102) comprising particles transparent to the emission wavelength of the light-emitting diode (101). The optical device (102) has conversion particles configured to emit, by converting a portion of the electromagnetic radiation emitted by the light-emitting diode (101), electromagnetic radiation according to an emission wavelength of the conversion particles included in the ultraviolet and strictly higher than the emission wavelength of the light-emitting diode (101).
