Patent number: 6911082Abstract: Multi-layered semiconductor nanoparticles having a very narrow grain-size distribution and exhibiting a spectrum having a narrow wavelength-width peak are prepared by a manufacturing method combining a monodisperse semiconductor nanoparticle manufacturing method and a multi-layer semiconductor nanoparticle preparation method. The nature of a solution of monodisperse semiconductor nanoparticles that is stabilized by a surface stabilizer is transformed between hydrophilic and lipophilic by substituting the surface stabilizer. The stabilized semiconductor nanoparticles are then shifted between an aqueous layer and an organic layer. The semiconductor nanoparticles are coated with multiple layers in the organic layer, and the organic layer is drawn off to recover the semiconductor nanoparticles therefrom.Type: GrantFiled: January 22, 2003Date of Patent: June 28, 2005Assignee: Hitachi Software Engineering Co., LTDInventors: Keiichi Sato, Susumu Kuwabata
