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.

摘要： Provided is means which enables observation of the shape of a specimen as it is without deforming the specimen. Observation is made by allowing a specimen-holding member having an opening (for example, microgrid and mesh) to hold an ionic liquid and charging a specimen thereto, to allow the specimen to suspend in the ionic liquid. Furthermore, in the proximity of the specimen-holding member, a mechanism of injecting an ionic liquid (ionic liquid introduction mechanism) and/or an electrode are provided. When a voltage is applied to the electrode, the specimen moves or deforms in the ionic liquid. How the specimen moves or deforms can be observed. Furthermore, in the proximity of specimen-holding member, an evaporation apparatus is provided to enable charge of the specimen into the ionic liquid while evaporating. Furthermore, in the proximity of the specimen-holding member, a microcapillary is provided to charge a liquid-state specimen into the ionic liquid. Note that the specimen-holding member is designed to be rotatable.

摘要： This invention provides semiconductor nanoparticles having fluorescence properties and comprising a modifying group represented by the following general formula bound to their surfaces, a method for producing the same, and a fluorescence reagent comprising semiconductor nanoparticles: —OY wherein Y is selected from a hydrogen atom, a metal atom, a semimetal atom, an organic group, or an organic group that is intermediated by a metal atom or a semimetal atom. In this method, the surfaces of the semiconductor nanoparticles were modified with a hydroxyl group or the like for stabilization. This realizes the production of semiconductor nanoparticles having fluorescence properties that significantly emit only the band gap fluorescence, the production of which at the industrial level was previously very difficult due to the necessity of many processes and from the viewpoint of technology and safety.

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.
