Publication number: 20090015919Abstract: The present invention has been developed for providing a method to easily manufacture a nanosized EuSe crystal which has been conventionally difficult to be manufactured. Heating the Eu(III) complex whose general formula is represented by the following formula generates an EuSe crystal having a particle size corresponding to the heating condition. Alternatively, the mixture composed of Eu(III) complex, a counter cation, and a solvent may be heated. Since the particle size of the nanosized EuSe crystals can be manipulated by the heating condition, the absorption wavelength of the EuSe crystals can be easily controlled. In addition, since it is easy to create a magnetooptic-responsive plastic using the high dispersibility of the EuSe crystals, it can be immediately applied to an optical isolator or other devices.Type: ApplicationFiled: February 23, 2007Publication date: January 15, 2009Applicant: National University Corporation Nara Institute Of Science and TechnologyInventors: Yasuchika Hasegawa, Tsuyoshi Kawai, Takaaki Adachi

Publication number: 20090009859Abstract: According to a circular dichroism fluorescent microscope 100, in one embodiment of the present invention, it is possible to analyze, by using a small amount of a sample and directly in a living organism, a high-order structure of the sample such as a biomolecule, for example, protein and the like. The circular dichroism fluorescent microscope includes a confocal section. In the circular dichroism fluorescent microscope, a circularly polarizing/modulating section converts, into right and left circularly polarized lights, a light beam emitted from a light source. Thus obtained right and left circularly polarized light is focused on the sample so that the sample is irradiated with the right and left circularly polarized lights. Then, an optical lens focuses fluorescence emitted from the sample. Further, a wavelength selecting section transmits only fluorescence having a predetermined wavelength. Subsequently, the fluorescence having passed through the wavelength selecting section is detected.Type: ApplicationFiled: February 1, 2007Publication date: January 8, 2009Inventors: Tsuyoshi Kawai, Kensuke Kawamura

Publication number: 20080298422Abstract: Although having been used for conventional dye laser solvents, organic solvents have a disadvantage of volatility and inflammability, which makes a dye laser device large and cumbersome. In the present invention, which has been developed to solve this problem, an ionic liquid is used as the dye laser solvent. An organic dye stably dissolves in an ionic liquid and the light-emitting property is almost comparable to the case where an organic solvent is used. Since ionic liquids do not have volatility and inflammability, the dye laser medium according to the present invention is extremely easy to handle. In addition, it also has a property that the photobleach is extremely low compared to conventional dye laser mediums using an organic solvent as the solvent thereof. It is easy to obtain a laser sensor for detecting a predetermined specimen with high sensitivity using the dye laser medium according to the present invention.Type: ApplicationFiled: January 26, 2007Publication date: December 4, 2008Applicant: NATIONAL UNIVERSITY CORPORATION NARA INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Tsuyoshi Kawai, Takuya Nakashima
