Abstract
(EN) The present disclosure relates to a composition comprising (i) a monomer, (ii) a photo initiator for photochemical polymerization of the monomer, (iii) a sensitizer, and (iv) quantum dots (QD). The present disclosure further relates to a method for photochemical polymerization of quantum dot-based color conversion filter (QD-CCF) matrices and/or for matrix curing, comprising the use of a combination of a sensitizer and a photo initiator. The present disclosure also relates to thin layers and a quantum dot-based color conversion filter (QD-CCF) matrix comprising a thin layer. Moreover, the present disclosure relates to the use of a thin layer as quantum dot-based color conversion filter (QD-CCF) and to a device comprising a quantum dot-based color conversion filter (QD-CCF).
(FR) La présente divulgation concerne une composition comprenant (i) un monomère, (ii) un photo-initiateur pour la polymérisation photochimique du monomère, (iii) un sensibilisateur et (iv) des points quantiques (QD). La présente divulgation concerne en outre un procédé de polymérisation photochimique de matrices de filtre de conversion de couleur à base de points quantiques (QD-CCF) et/ou pour le durcissement de matrice, comprenant l'utilisation d'une combinaison d'un sensibilisateur et d'un photo-initiateur. La présente divulgation concerne également des couches minces et une matrice de filtre de conversion de couleur à base de points quantiques (QD-CCF) comprenant une couche mince. De plus, la présente divulgation concerne l'utilisation d'une couche mince comme filtre de conversion de couleur à base de points quantiques (QD-CCF) et un dispositif comprenant un filtre de conversion de couleur à base de points quantiques (QD-CCF).
