摘要:
Described herein are batches of nanoscale phosphor particles having an average particle size of less than about 200 nm and an average internal quantum efficiency of at least 40%. The batches of nanoscale phosphor particles can be substantially free of impurities. Also described herein are methods of manufacturing the nanoscale phosphor particles by passing phosphor particles through a reactive field to thereby dissociate them into elements and then synthesizing nanoscale phosphor particles by nucleating the elements and quenching the resulting particles.

摘要:
Embodiments of the present invention relate to semiconducting carbon-containing devices and methods of making thereof. The semi-conducting carbon containing devices comprise an n-type semiconducting layer and a p-type semiconducting layer, both of which are positioned over a substrate. The n-type semiconducting layer can be formed by pyrolyzing a carbon- and nitrogen-containing polymer, and the p-type semiconducting layer can be formed by pyrolyzing an aromatic- and aliphatic-group-containing polymer. In some embodiments, the devices are solar cell devices.

摘要:
A solvothermal process for making inorganic nanoparticles is described. Inorganic nanoparticles can be produced by forming a suspension or solution comprising at least one group II-IV and lanthanide metal inorganic salt in a first medium, disposing the suspension or solution in a sealed chamber having an interior pressure, elevating the interior pressure of the sealed chamber to an initial interior pressure prior to the heating, heating the suspension or solution to a peak temperature higher than the normal boiling point of the first medium, optionally adding a second medium to the suspension or solution after the heating.

摘要:
Photoinduced chemical vapor deposition was used to grow coatings on nanoparticles. Aerosolized nanoparticles were mixed with a vapor-phase coating reactant and introduced into a coating reactor, where the mixture was exposed to ultraviolet radiation. Tandem differential mobility analysis was used to determine coating thicknesses as a function of initial particle size.
摘要:
The invention provides a process of manufacturing an optical waveguide for optically connecting a plurality of optical devices, comprising the steps of: disposing a resin composition between two or more optical devices, the resin composition comprising a resin and a 1,4-dihydropyridine derivative, forming an optical path through the resin composition between the optical devices by light having a wavelength capable of inducing a structural change in the 1,4-dihydropyridine derivative, and removing the 1,4-dihydropyridine derivative from the resulting resin composition. Also disclosed is a connection structure obtained by the process.
