Patent number: 8648136Abstract: Polymer-inorganic particle blends are incorporated into structures generally involving interfaces with additional materials that can be used advantageously for forming desirable devices. In some embodiments, the structures are optical structures, and the interfaces are optical interfaces. The different materials at the interface can have differences in index-of-refraction to yield desired optical properties at the interface. In some embodiments, structures are formed with periodic variations in index-of-refraction. In particular, photonic crystals can be formed. Suitable methods can be used to form the desired structures.Type: GrantFiled: October 5, 2010Date of Patent: February 11, 2014Assignee: NanoGram CorporationInventors: Nobuyuki Kambe, Christian C. Honeker, Yigal Dov Blum, David Brent MacQueen
