Abstract
Quantum dot polymer composites for on-chip light emitting diode applications are described. In an example, a composite for on-chip light emitting diode application includes a polymer matrix, a plurality of quantum dots dispersed in the polymer matrix, and a base dispersed in the polymer matrix.
Claims32
A method of fabricating a composite for on-chip light emitting diode application, the method comprising:
- adding a base chemical compound to a plurality of quantum dots to form a mixture comprising at least a remainder portion of the base chemical compound;
- and
- adding the mixture to a polymer matrix.
A method of fabricating a composite for on-chip light emitting diode application, the method comprising:
- forming a mixture of a plurality of quantum dots and a first component of a two-part silicone formulation;
- heating the mixture;
- and
- subsequent to heating the mixture, adding the mixture to a second component of the two-part silicone formulation.
A method of fabricating a composite for on-chip light emitting diode application, the method comprising:
- forming a solution of a plurality of quantum dots in a first solvent;
- removing the first solvent and redissolving the plurality of quantum dots in a second, different, solvent;
- and
- subsequent to redissolving the plurality of quantum dots in the second solvent, dispersing the plurality of quantum dots in a polymer matrix.
