Abstract
There are provided a microcapsular quantum dot-polymer composite, a method for producing the composite, optical elements, and a method for producing the optical elements. In order to produce the microcapsular quantum dot-polymer composite, a polymer having a functional group in the side chain is firstly heated in a first solvent to form a polymer solution. A quantum dot suspension consisting of quantum dots capped by a capping layer dispersed in a second solvent is added to the polymer solution to form a mixed solution. The mixed solution is cooled to form the quantum dot-polymer composite consisting of the quantum dots dispersed in the polymer matrix.
