Crystal growth performed in situ facilitates interconnection of prefabricated nano-structures. The nano-structures are immersed in a growth solution having a controllable saturation condition. Changing the saturation condition of the solution modifies a size of the immersed nanowires. The solution includes a solute of a nano-structure precursor material. The saturation condition is changed to one or both etch material from a surface of the nano-structures and initiate crystal growth on the nano-structure surface. A nano-structure interconnection system includes the growth solution and equipment to deposit the prefabricated nano-structures on a substrate. An interconnected structure includes a plurality of nano-structures disposed on a substrate in a cluster and a liquid phase-grown crystal lattice on surfaces of the nano-structures to form physical interconnections between the plurality. An ink formulation includes the plurality of nano-structures suspended in the growth solution.

A self-aligning nanowire includes a nanowire portion and an aligning member attached to the nanowire portion. The aligning member interacts with another aligning member on an adjacent self-aligning nanowire to align the nanowires together. A method of aligning nanowires includes providing a plurality of the self-aligning nanowires, suspending the plurality in a carrier solution, and depositing the suspended plurality on a substrate. An ink formulation includes the plurality of suspended self-aligning nanowires in the carrier solution. A method of producing the self-aligning nanowire includes providing and associating the nanowire portion and the aligning member such that the nanowire produced is self-aligning with another nanowire.

Compositions and methods for production of conductive paths can include a printable composition including a liquid carrier and a plurality of nanostructures. The plurality of nanostructures can have an aspect ratio of at least about 5:1 within the liquid carrier. Examples of nanostructures include nanobelts, nanoplates, nanodiscs, nanowires, nanorods, and mixtures of these materials. These printable compositions can be used to form a conductive path on a substrate. The printable composition can be applied to a substrate using any number of conventional printing techniques. Following application of the printable composition, at least a portion of the liquid carrier can be removed such that the nanostructures can be in sufficient contact to provide a conductive path. The nanostructures arranged in a conductive path can be sintered or used as a conductive material without sintering.

A printable composition for use in forming a printed element by printing and curing is described. The printable composition comprises a plurality of nanostructures of a first type that, upon printing and curing, form an arrangement defining intermediate volumes thereamong. The printable composition further comprises a plurality of nanostructures of a second type that, upon printing and curing, at least partially fill the intermediate volumes to promote smooth surface topography and reduced porosity in the printed element.

A phosphor composition comprises a host lattice, a dopant and a decay modifying component different from the dopant and the host lattice and effective to alter the rate of decay of the radiation emitted by the phosphor composition in response to excitation by photons of a given energy. The decay modifying component is added to the phosphor composition in a predetermined amount between 1 and 10,000 parts per million of the composition. By varying the amount of the decay modifying component added to the phosphor composition, it is possible to produce a set of phosphor compositions with different, controlled rates of decay of the radiation emitted by the compositions.
摘要:
Compositions, inks and methods for forming a patterned silicon-containing film and patterned structures including such a film. The composition generally includes (a) passivated semiconductor nanoparticles and (b) first and second cyclic Group IVA compounds in which the cyclic species predominantly contains Si and/or Ge atoms. The ink generally includes the composition and a solvent in which the composition is soluble. The method generally includes the steps of (1) printing the composition or ink on a substrate to form a pattern, and (2) curing the patterned composition or ink. In an alternative embodiment, the method includes the steps of (i) curing either a semiconductor nanoparticle composition or at least one cyclic Group IVA compound to form a thin film, (ii) coating the thin film with the other, and (iii) curing the coated thin film to form a semiconducting thin film. The semiconducting thin film includes a sintered mixture of semiconductor nanoparticles in hydrogenated, at least partially amorphous silicon and/or germanium. The thin film exhibits improved conductivity, density, adhesion and/or carrier mobility relative to an otherwise identical structure made by an identical process, but without either the semiconductor nanoparticles or the hydrogenated Group IVA element polymer. The present invention advantageously provides semiconducting thin film structures having qualities suitable for use in electronics applications, such as display devices or RF ID tags, while enabling high-throughput printing processes that form such thin films in seconds or minutes, rather than hours or days as with conventional photolithographic processes.
