Abstract
(EN)
The present invention relates to an optoelectronic device (10) comprising a substrate (12), at least hydrophilic photoluminescent blocks (23) comprising hydrophilic photoluminescent particles (24) covering first regions (16) of the substrate and hydrophobic photoluminescent blocks (25) comprising hydrophobic photoluminescent particles (26) covering second regions (18) of the substrate, the hydrophilic photoluminescent blocks being in contact with a hydrophilic material (20) in the first regions and the hydrophobic photoluminescent blocks being in contact with a hydrophobic material (22) in the second regions.
