Patent ID: 7374807

Claim:
A polymeric layer in combination with an optical device, comprising: (a) a polymer; (b) semiconductor nanocrystals; (c) a ligand composition attached to the nanocrystals wherein the ligand composition is different from the polymer, wherein the nanocrystals with ligand composition attached thereto are mechanically embedded within said polymer, the ligand composition comprising a body structure comprising an alkane chain of 4 carbons or between 6 and 22 carbons in length, a head group chemically coupled to the nanocrystals and to the body structure at a first position on the alkane chain and a tail group chemically coupled to the body structure at a second position on the alkane chain, wherein the tail group comprises one or more silicon groups or one or more terminal hydroxyl groups; and (d) an optical device, wherein said polymeric layer encapsulates the optical device and scatters less than about 50% of incident light that enters said layer from said optical device.
