Patent number: 8425803Abstract: 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 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.Type: GrantFiled: November 9, 2009Date of Patent: April 23, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: J. Wallace Parce, Paul Bernatis, Robert Dubrow, William P. Freeman, Joel Gamoras, Shihai Kan, Andreas Meisel, Baixin Qian, Jeffery A. Whiteford, Jonathan Ziebarth
