摘要： The present invention relates to a novel method for preparing a water-insoluble metal hydroxide, and a use thereof. The water-insoluble metal hydroxide of the present invention is conveniently and efficiently prepared s through the high-temperature heat treatment step two times and the washing step, and thus contains a small amount of an alkali metal and has a high crystallinity and a phase purity. The water-insoluble metal hydroxide of the present invention or metal oxide therefrom exhibits an absorption wavelength at a low wavelength range (for example, 490 nm or less) and a light emitting wavelength at a high wavelength range (for example, from 500 nm or more to less than 1,100 nm). Accordingly, the water-insoluble metal hydroxide of the present invention may be efficiently used in various applications such as a fire retardant, an antacid, an adsorbent and so forth, and may also be doped with another metal ion to be utilized as a raw material for fabricating a catalyst, a fluorescent material, an electrode material, a secondary battery material and the like.

摘要： A nanocrystal electroluminescence device comprising a polymer hole transport layer, a nanocrystal light-emitting layer and an organic electron transport layer wherein the nanocrystal light-emitting layer is independently and separately formed between the polymer hole transport layer and the organic electron transport layer. According to the nanocrystal electroluminescence device, since the hole transport layer, the nanocrystal light-emitting layer and the electron transport layer are completely separated from one another, the electroluminescence device provides a pure nanocrystal luminescence spectrum having limited luminescence from other organic layers and substantially no influence by operational conditions, such as voltage. Further, a method for fabricating the nanocrystal electroluminescence device.

摘要： Nano-silicates are the template for photonic control materials with research for a material allowing three-dimensional (3-d) photonic control ongoing for years. This author discovered a material that physically enables 3-d photonic control over the visible spectrum via the previously unidentified property of coherent poly propagation (CPP). CPP allows actualized 3-d photonic demultiplexing in several precious opal nano-silicate specimens. This is a working material that accurately demultiplexes, up/downconverts and propagates the shapes of several types of mono and polychromatic incident light sources. This material is a durable 3-d demultiplexing photonic waveguide that works without cables. The propagated shapes are able to be manually moved across the 3-d specimen surfaces. Other, previously unknown, properties displayed by this material: spectrophotometric and polariscopic play-of-color, plus photonic rotational symmetry. This material is environmentally friendly, in that it emits no beta or alpha particles, performs at ambient temperatures/pressures and is made of commonly available silica.

摘要： An article that includes a fluorescent composition having at least one of a fluorescent sensor compound and organic reporter molecules encapsulated in a microsphere structure. When encapsulated, the fluorescent sensor compound and the organic reporter molecules are distributed in a liquid organic matrix. When non-encapsulated, the remaining one of the fluorescent sensor compound and the organic reporter molecules reside in the matrix. In response to a force applied to the composition sufficient to break at least a portion of the microsphere structure, the fluorescent sensor compound and the organic reporter molecules are transformed into a non-reversible fluorescent state exhibiting a quantum yield greater than 0.2. The fluorescent state is objectively visually verifiable without physically contacting the composition.

摘要： Disclosed are a quantum dot light emitting device, a preparation method thereof and a display apparatus. In embodiments of the present disclosure, at least one of one or more light emitting function layers is disposed to include at least two sub-function layers, each sub-function layer includes ligands, and surface energy of the ligands corresponding to the sub-function layers gradiently changes in a transmission direction of carriers in the sub-function layers, so that energy levels of the sub-function layers gradiently change. In this way, the energy levels of the sub-function layers can be matched with energy levels of the adjacent light emitting function layers.
