Abstract
A photosensitive composition, a quantum dot polymer composite pattern prepared therefrom, and a layered structure and an electronic device including the same. The photosensitive composition includes plurality of quantum dots; a luminescent material other than a quantum dot; a carboxylic acid group containing binder; a photopolymerizable monomer having a carbon-carbon double bond; and a photoinitiator, and the luminescent material comprises a fluorophore, a nanosized inorganic phosphor, or a combination thereof.
Claims23
A photosensitive composition comprising:
- a quantum dot;
- a luminescent material other than a quantum dot, wherein a weight ratio of the luminescent material with respect to the quantum dot is greater than or equal to about 10−4:1 and less than or equal to about 0.1:1;
- a carboxylic acid group-containing binder;
- a photopolymerizable monomer comprising a carbon-carbon double bond;
- and
- a photoinitiator,
- wherein the luminescent material comprises a fluorophore, an inorganic phosphor, or a combination thereof.
A quantum dot-polymer composite comprising:
- a polymer matrix;
- a plurality of quantum dots;
- and
- a luminescent material other than a quantum dot, wherein a weight ratio of the luminescent material with respect to the quantum dot is greater than or equal to about 10−4:1 and less than or equal to about 0.1:1;
- wherein the quantum dots and the luminescent material are dispersed in the polymer matrix;
- wherein the luminescent material comprises a fluorophore, an inorganic phosphor, or a combination thereof;
- and
- wherein the plurality of the quantum dots absorb at least a portion of light emitted from the luminescent material.
