Abstract
A light emitting system includes a polymer mixture, and a plurality of nanocrystals occupying a predetermined portion of the polymer mixture. The polymer mixture includes at least two polymers that phase-segregate. Method(s) for controlling nanocrystal distribution within the light emitting device are also disclosed.
Claims16
A light emitting system, comprising:
- a polymer mixture including at least two partially miscible or non-miscible different polymers that segregate, the polymer mixture having a thickness ranging from about 10 nm to about 1000 nm;
- and
- a controlled distribution of a plurality of nanocrystals occupying predefined, discrete positions of the polymer mixture, the controlled distribution being achieved due to properties of the at least two partially miscible or non-miscible different polymers selected for the polymer mixture and properties of the plurality of nanocrystals selected for the polymer mixture.
