Abstract
A light-emitting element includes: a first electrode; a second electrode; and a quantum-dot layer; provided between the first electrode and the second electrode. The quantum-dot layer contains a plurality of quantum dots including at least cores, and an inorganic filler material filling spaces between the plurality of quantum dots. At least a portion of a composition of the quantum-dot layer around at least one core has a concentration gradient in a direction from toward a center of the core to toward around the core.
Claims21
A light-emitting element, comprising:
- a first electrode;
- a second electrode;
- and
- a quantum-dot layer positioned between the first electrode and the second electrode, and containing a plurality of quantum dots including at least cores, and an inorganic filler material filling spaces between the plurality of quantum dots, at least a portion of a composition of the quantum-dot layer around at least one of the cores having a concentration gradient in a direction from toward a center of the at least one core to toward around the core.
A method for producing a light-emitting element including:
- a first electrode;
- a second electrode;
- and a quantum-dot layer positioned between the first electrode and the second electrode, and containing a plurality of quantum dots including at least cores, and an inorganic filler material filling spaces between the plurality of quantum dots, the method comprising:
- a synthesizing step of synthesizing the quantum dots;
- a forming step of forming the quantum-dot layer containing the inorganic filler material and the quantum dots synthesized at the synthesizing step;
- and at least one of
- a first step of synthesizing the quantum dots at the synthesizing step, the quantum dots each including one of the cores and a shell positioned partially around the one core, and at least a portion of a composition of the shell having a concentration gradient from toward a center of the core to toward around the core, or
- a second step of forming the quantum-dot layer at the forming step, at least a portion of a composition of the inorganic filler material having a concentration gradient from toward the center of at least one of the cores to toward around the core.
(canceled)
A light-emitting element, comprising:
- a first electrode;
- a second electrode;
- and
- a quantum-dot layer positioned between the first electrode and the second electrode, and containing a plurality of quantum dots including at least cores, and an inorganic filler material filling spaces between the plurality of quantum dots, at least a portion of a composition of the quantum-dot layer around at least one of the cores having a concentration gradient, leading to the inorganic filler material, in a direction from toward a center of the at least one core to toward around the core.
