  • Method and apparatus for fabricating quantum dot functional structure, quantum dot functional structure, and optically functioning device
    Patent number: 7384666
    Abstract: Fabrication of a quantum dot functional structure having ultra-fine particles homogeneously distributed in a transparent medium includes depositing such particles having a single particle diameter and uniform structure onto a substrate with the transparent medium.
    Type: Grant
    Filed: September 9, 2003
    Date of Patent: June 10, 2008
    Assignees: Matsushita Electric Industrial Co., Ltd., Japan as represented by Director General of National Institute of Advanced Industrial Science and Technology, Ministry of Economy, Trade and Industry
    Inventors: Nobuyasu Suzuki, Toshiharu Makino, Yuka Yamada, Takehito Yoshida, Takafumi Seto, Nobuhiro Aya
  • Method for separating particles different in size, structure, or function and apparatus therefor
    Publication number: 20050155910
    Abstract: A method and an apparatus for separating fine particles of different fine particle sizes, structures, and functions are provided. The method includes the steps of introducing a group of fine particles of different sizes, structures, and functions into an atmosphere of an adsorption fluid; effecting critical adsorption of the adsorption molecular species to specific sites of the fine particles and, subsequently, separating the fine particles according to size, structure, or function based on one of the masses, the particle diameters, the fluid resistances, and the functions of adsorption abilities to a third substance, which have been changed due to the critical adsorption, or at least two of them in combination.
