A tunable fluorescent quantum dot may be utilized for illumination of artificial reality displays or waveguides. The tunable quantum dot may include a core fluorescence quantum dot and multiple coatings that may activate based on different wavelengths of one or more activation energies. Un point quantique fluorescent accordable peut être utilisé pour l'éclairage d'affichages ou de guides d'ondes de réalité artificielle. Le point quantique accordable peut comprendre un point quantique à fluorescence de coeur et de multiples revêtements qui peuvent s'activer sur la base de différentes longueurs d'onde d'une ou de plusieurs énergies d'activation.
