Abstract:
1. A method for fabricating a quantum dot functional structure comprising: generating fine particles, classifying said fine particles generated according to a desired particle diameter in a gas, exhausting the gas for transporting said fine particles after said classifying, collecting said classified fine particles onto a substrate and generating a transparent medium at the same time, and depositing said classified fine particles and said transparent medium onto said substrate at the same time, wherein in said fine particles classifying step, charged ultra-fine particles are classified in a classifying region by making use of electrical mobility being dependent on a particle diameter of charged particles upon application of an electrostatic field thereto in a viscous fluid, said classifying region employing a space defined between two concentric disks, spaced apart from each other and arranged in parallel to each other; and said charged ultra-fine particles are classified in two or more multi-stages in which three or more of said concentric disks are arranged to thereby constitute said classifying region.
