摘要： Provided herein are embodiments of a three-dimensional bicontinuous heterostructure, a method of producing same, and the application of this structure. The three-dimensional bicontinuous heterostructure includes two interpenetrating layers which are spatially continuous, include only protrusions or peninsulas, and have no islands. The method of producing the three-dimensional bicontinuous heterostructure includes forming an essentially planar continuous bottom layer of a first material; forming a layer of this first material on top of the bottom layer that is textured to produce protrusions for subsequent interpenetration with a second material, coating this second material onto this structure, and forming a coating with the second material that ensures that only the second material is contacted by subsequent layer. One of the materials includes visible and/or infrared-absorbing semiconducting quantum dot nanoparticles, and one of materials is a hole conductor and the other is an electron conductor.

摘要： Optical and optoelectronic devices and methods of making same. Under one aspect, an optical device includes an integrated circuit an array of conductive regions; and an optically sensitive material over at least a portion of the integrated circuit and in electrical communication with at least one conductive region of the array of conductive regions. Under another aspect, a method of forming a nanocrystalline film includes fabricating a plurality of nanocrystals having a plurality of first ligands attached to their outer surfaces; exchanging the first ligands for second ligands of different chemical composition than the first ligands; forming a film of the ligand-exchanged nanocrystals; removing the second ligands; and fusing the cores of adjacent nanocrystals in the film to form an electrical network of fused nanocrystals. Under another aspect, a film includes a network of fused nanocrystals, the nanocrystals having a core and an outer surface, wherein the core of at least a portion of the fused nanocrystals is in direct physical contact and electrical communication with the core of at least one adjacent fused nanocrystal, and wherein the film has substantially no defect states in the regions where the cores of the nanocrystals are fused.
