Presentation Summary

Semiconductor nanocrystals, also commonly called quantum dots (QDs), are attracting widespread attention because of unique
optical properties, including emission wavelengths in the visible range, high quantum efficiency, narrow emission with wide absorption profiles, and compatibility with custom matrix polymers. Dispersion in a custom polymer requires 1.) modifying the surface of the QDs to isolate them from the degrading effects of oxygen and water vapor, and 2.) developing a custom host polymer matrix optimized for the QD surface interaction.
 
Traditional approaches to QD dispersion require the use of small molecule surfactants as additives or functionalized block-copolymers
as the matrix, or a combination of both. A number of challenges exist with these systems due to their complexity. Crystalplex polymer-QD composites can survive thermoplastic injection molding and extrusion conditions without a decrease in quantum efficiency or photostability of the nanocrystals. This opens up new opportunities for high-performance optical components.
