Abstract
An optoelectronic device including light-emitting components, each light-emitting component being adapted to emit a first radiation at a first wavelength, and photoluminescent blocks, each photoluminescent block facing at least one light-emitting component and comprising a single quantum well or multiple quantum wells, photoluminescent blocks being divided into first photoluminescent blocks adapted to convert by optical pumping the first radiation into a second radiation at a second wavelength, second photoluminescent blocks adapted to convert by optical pumping the first radiation into a third radiation at a third wavelength and third photoluminescent blocks adapted to convert by optical pumping the first radiation into a fourth radiation at a fourth wavelength.
