US Patent 7065285 -Quantum Dots in Aromatic Polymer Matrix
http://www.freepatentsonline.com/7065285.pdf
A variety of glass and polymer materials have been used to construct optical fibers, optical amplifiers, optical switches, and various other optical devices. Typically polymer materials are less favored because, even though polymers are generally tougher more durable than glass materials, polymers produce greater signal attenuation. This patent proposes the use of quantum dots in an aromatic (C6H6 based) polymer to facilitate the production of improved optical waveguides and other optical devices. Claim 8 is representative:
8. A composition of matter, comprising: a polymer matrix including polymer chains having a plurality of carbon-fluorine bonds; and a plurality of quantum dots distributed within the polymer matrix, wherein the polymer chains include aromatic groups.
