CPC H01L 33/504 (2013.01) [H01L 2933/0041 (2013.01)] | 27 Claims |
1. An optoelectronic device comprising a support, at least hydrophilic photoluminescent blocks comprising hydrophilic photoluminescent particles covering first areas of the support and hydrophobic photoluminescent blocks comprising hydrophobic photoluminescent particles covering second areas of the support, the hydrophilic photoluminescent blocks being in contact with a hydrophilic material at the level of the first areas and the hydrophobic photoluminescent blocks being in contact with a hydrophobic material at the level of the second areas,
wherein the hydrophilic material comprises first hydrophilic ligands, each comprising a hydrophilic chain, a first group at a first end of the hydrophilic chain, bonded to a hydroxy group at the surface of the support, and a second group at a second end of the hydrophilic chain, opposite to the first end, in contact with one of the hydrophilic photoluminescent blocks.
