摘要: A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

摘要: The purpose is to provide a wavelength conversion member, a method for manufacturing the wavelength conversion member, and a light-emitting device, which are capable of reducing the temperature rise of the wavelength conversion member and thus reducing the decrease in luminescence intensity with time and deformation and discoloration of constituent materials. A wavelength conversion member 10 includes a matrix 1 and phosphor particles 3 dispersed in the matrix 1, wherein the matrix 1 is formed of a porous oxide body 2 having an average pore diameter of 50 μm or less.

摘要: The present invention relates to organic light emitting devices with a multi-emissive material layer (EML), where a multi-EML generally refers to an emissive layer having at least two layers of emissive material, each layer having a different emitter concentration (e.g. a first EML in direct contact with a second EML, and the emitter concentration of the first EML (hole favorable) exceeds that of the second EML (electron favorable)).

摘要: Multi-phase polymer films containing quantum dots (QDs) are described herein. The films have domains of primarily hydrophobic polymer and domains of primarily hydrophilic polymer. QDs, being generally more stable within a hydrophobic matrix, are dispersed primarily within the hydrophobic domains of the films. The hydrophilic domains tend to be effective at excluding oxygen.

摘要: A modified perovskite quantum dot material, a fabricating method thereof, and a display device are provided. Hydroxyl-modified perovskite quantum dots are obtained by adding an excess amount of hydroxyl-containing surface ligands to a solution of synthesized perovskite quantum dots. After high-speed centrifugation, the obtained perovskite quantum dots are redispersed into a non-polar alkyl solvent to form a solution. Further, an excess amount of ethyl orthosilicate is added to the solution, and after exposing the solution for a long period of time, the ethyl orthosilicate is hydrolyzed to form a triethoxysilane group. After centrifugation, modified perovskite quantum dots wrapped by the triethoxysilane groups are obtained, which effectively improves stability of the perovskite quantum dots.
