Abstract: Present invention is related to a metallic particle-deposition substrate having a metal substrate and multiple metallic particles attached thereon. The metallic particles are nano-particles with at least 90% of these nano-particles as single layer being evenly dispersed on the metal substrate. Each of the metallic particle is isolated without toughing or overlapping. The metal substrate has different material than the metallic particles in each preferred embodiment in the present invention. More preferably, at least 80% of the metallic particles have the distance between each metallic particle is at a range of 2-6 nm for better generation of hotspot effects. The present invention provides a fast production method for producing the substrate with heterogeneous interface. The metallic particles are evenly attached to the surface of the metal substrate to obtain better surface enhanced Raman effect as to apply for sensors in all kinds of field.

Abstract: A method of manufacturing a composite catalyst is provided. The method includes the following steps. A catalyst composition including an inorganic support and a metallic nanoparticle attached to a surface of the inorganic support is provided. The catalyst composition, an organic material, and an acidic solvent are mixed to obtain a first mixed solution. An oxidant and the first mixed solution are mixed to obtain a second mixed solution. A drying process is performed on the second mixed solution to remove a solvent in the second mixed solution and to obtain a solid composite catalyst precursor. A calcination process is performed on the composite catalyst precursor to form a carbon-decorated composite catalyst.

Abstract: A laminated optical disk, applied for lighting system or solar energy system, includes a plurality of annular lenses, a base and a circular light guiding unit. The annular lenses are arranged in order from center to outside to form a disk-structure. Each annular lens has a light-input curved surface and a light-output curved surface respectively matching the different thickness of the base. The light-input curved surface is opposite to the center. The light-output curved surface is opposite to the light-input curved surface, and facing to the center. The light is incident on the light-input curved surface, refracted and tended to concentrate by the light-input curved surface. Besides, the light exiting from the annular lens is to be refracted to the direction of the center by the light-output curved surface. The base of the laminated optical disk can significantly improve the light leakage problem by different annular lenses.
Abstract translation: 应用于照明系统或太阳能系统的层压光盘包括多个环形透镜，基座和圆形导光单元。 环形透镜从中心到外侧依次布置以形成盘结构。 每个环形透镜都具有分别与底座不同厚度匹配的光输入曲面和光输出曲面。 光输入曲面与中心相反。 光输出曲面与光输入曲面相对，面向中心。 光入射在光输入曲面上，折射并倾向于通过光输入曲面集中。 此外，从环形透镜出射的光将被光输出曲面折射到中心的方向。 层叠光盘的底座可以显着改善不同环形透镜的漏光问题。
