摘要： A core-shell structure comprises a core (2) comprising nanoparticles and a shell (4) coating the core (2), and its void space (3) formed by the core (2) and the shell (4) is controlled. A method of preparing the core-shell structure comprises: forming particles comprising a photoetchable semiconductor, metal or polymer and coating the particles with a shell (4) comprising a non-photoetchable semiconductor, metal or polymer, to form a core-shell structure (5); and irradiating the core-shell structure with a light having a controlled wavelength in the photoetching solution to form an adjustable void space inside a shell (3) within the core-shell structure by the size-selective photoetching method. The core-shell structure allows the preparation of a catalyst exhibiting an extremely high efficiency, and can be used as a precursor for preparing a nanomaterial required for a nanodevice.

摘要： Copper(II) acetate, zinc(II) acetate, and tin(IV) acetate are weighed so that the total amount of metal ions is 2.0×10−4 mol and the molar ratio of ions is Cu:Zn:Sn=2:1:1, and 2.0 cm3 of oleylamine is added to prepare a mixed solution. Apart from this, 1.0 cm3 of oleylamine is added to 2.0×10−4 mol of sulfur powder to prepare a mixed solution. These mixed solutions are separately heated at 60° C. and mixed at room temperature. The pressure in a test tube is reduced, followed by nitrogen filling. The test tube is heated at 240° C. for 30 minutes and then allowed to stand until room temperature. The resultant product is separated into a supernatant and precipitates by centrifugal separation. The separated supernatant is filtered, methanol is added to produce precipitates. The precipitates are dissolved by adding chloroform to prepare a semiconductor nanoparticle solution.

摘要： An object of the present invention is to provide a medium; a specimen; a method for preparing the specimen; a method for observing the specimen; a sample cell; and an electron microscope capable of easily solving the problem of charge-up and further capable of observing a real shape or the like of a sample with a SEM, a TEM or the like. For the purpose of achieving the above-described object, the present invention uses an electrical conductivity-imparting liquid medium, for use in a microscope, which includes an ionic liquid as an essential component thereof and is impregnated into the entirety of a SEM or TEM sample or applied to the observation surface of a SEM or TEM sample to impart electrical conductivity at least to the observation surface of the sample. According to the present invention, the charge built up on the sample surface can be released simply by impregnating or coating the sample with the ionic liquid, and hence the problem of charge-up can be easily solved. Further, even when a sample impregnated or coated with the ionic liquid is placed under vacuum, the ionic liquid is not evaporated from the sample, and hence a biological sample can be observed as it is in an original shape.

摘要： The present invention provides a method for producing nanoparticles by attaching atoms or molecules constituting a nanoparticle precursor to an ionic liquid. According to this method, it is possible to produce nanoparticles that do not aggregate easily in a liquid without its surface modification. Furthermore, it is possible to produce nanoparticles without the need for a complicated operation or the formation of a by-product because of the direct production of the nanoparticles from the nanoparticle precursor.
