Abstract: A method of synthesis of two-dimensional (2D) nanoflakes comprises the cutting of prefabricated nanoparticles. The method allows high control over the shape, size and composition of the 2D nanoflakes, and can be used to produce material with uniform properties in large quantities. Van der Waals heterostructure devices are prepared by fabricating nanoparticles, chemically cutting the nanoparticles to form nanoflakes, dispersing the nanoflakes in a solvent to form an ink, and depositing the ink to form a thin film.

Abstract: By forming nanoparticles from gas-phase precursors within cracks or defects in a gas-barrier film, crack-width may be determined from the diameter of the nanoparticles formed within. The optical absorption and emission wavelengths of a quantum dot are governed by the particle size. For a particular material, the absorption and/or emission wavelengths may therefore be correlated to the particle size (as determined from techniques such as transmission electron microscopy, TEM). Thus, fluorescence measurement techniques and/or confocal microscopy may be used to determine the size of quantum dots formed within a gas-barrier film, allowing both the size and nature of a defect to be determined. The method may be used to assess the potential effects of defects on the integrity of the gas-barrier film.

Abstract translation: 通过在气体阻隔膜的裂纹或缺陷内形成来自气相前体的纳米颗粒，可以从其内形成的纳米颗粒的直径确定裂纹宽度。 量子点的光吸收和发射波长由粒径决定。 对于特定材料，吸收和/或发射波长因此可以与粒度相关（由透射电子显微镜，TEM等技术确定）。 因此，可以使用荧光测量技术和/或共焦显微镜来确定在阻气膜内形成的量子点的尺寸，从而允许确定缺陷的尺寸和性质。 该方法可以用于评估缺陷对阻气膜的完整性的潜在影响。

Abstract: An emissive layer of an electroluminescent device, such as an electroluminescent display device, includes a host matrix and a two-dopant system dispersed in the host matrix. The two-dopant system has a fluorescent emitter dopant and an emissive donor-assistant dopant. The emissive donor-assistant dopant can be a fluorescence donor-assistant dopant or a phosphorescence donor- assistant dopant. The physical distance between the fluorescent emitter dopant and the emissive donor-assistant dopant can be controlled by using various capping ligands, which are bound to a surface of the fluorescent emitter dopant.

Abstract: Nanoparticles containing lUPAC group 11 ions, group 13 ions and sulfur ions are synthesized by adding metal salts and an alkanethiol in an organic solvent and promoting the reaction by applying heat. Nanoparticles are formed at temperatures as low as 200°C. The nanoparticles may be thermally annealed for a certain amount of time at a temperature lower than the reaction temperature (usually ~40°C lower) to improve the topology and narrow the size distribution. After the reaction is complete, the nanoparticles may be isolated by the addition of a non-solvent and re-dispersed in organic solvents including toluene, chloroform and hexane to form a nanoparticle ink. Additives may be incorporated in the reaction solution to tailor the final ink viscosity.

More particularly, the present invention provides a method for producing aqueous compatible semiconductor nanoparticles by binding pre- modified ligands to the nanoparticles without the need for further post-binding modification to render the nanoparticles aqueous compatible. Nanoparticles modified in this way can exhibit enhanced fluorescence and stability compared to aqueous compatible nanoparticles producing using prior art methods requiring post-binding modification processes.
