    摘要: Matrixes doped with semiconductor nanocrystals are provided. In certain embodiments, the semiconductor nanocrystals have a size and composition such that they absorb or emit light at particular wavelengths. The nanocrystals can comprise ligands that allow for mixing with various matrix materials, including polymers, such that a minimal portion of light is scattered by the matrixes. The matrixes are optionally formed from the ligands. The matrixes of the present invention can also be utilized in refractive index matching applications. In other embodiments, semiconductor nanocrystals are embedded within matrixes to form a nanocrystal density gradient, thereby creating an effective refractive index gradient. The matrixes of the present invention can also be used as filters and antireflective coatings on optical devices and as down-converting layers. Processes for producing matrixes comprising semiconductor nanocrystals are also provided. Nanostructures having high quantum efficiency, small size, and/or a narrow size distribution are also described, as are methods of producing indium phosphide nanostructures and core-shell nanostructures with Group II-VI shells.

    摘要: The method for manufacturing contact lenses includes the following steps. First, a first siloxane macromer, a second siloxane macromer, at least one hydrophilic monomer, an initiator and a solvent are mixed to form a mixture. Then the mixture is injected into a mold of contact lens and conducted by a thermal treatment or a UV irradiating treatment to form contact lenses. The number average molecular weight of the first siloxane macromer represented by the following formula (I), is 1,000 to 10,000 and the first siloxane macromer has a cross-linking function. The second siloxane macromer is selected from the group consisting of a siloxane macromer represented by the following formula (II) and a siloxane macromer represented by the following formula (III). Wherein in formula (II), p is an integer of 4 to 80, and in formula (III), q is an integer of 4 to 80 and r is an integer of 3 to 40.
