Method and apparatus for fabricating quantum dot functional structure, quantum dot functional structure, and optically functioning device

The apparatus for fabricating a quantum dot functional structure comprising:

• a fine particle generating chamber for generating fine particles,
• a fine particle classifying chamber for classifying the fine particles generated in said fine particle generating chamber according to a desired particle diameter in a gas,
• gas exhaust means for exhausting a gas for transporting said fine particles,
• transparent medium generating means for generating a transparent medium, and
• a depositing chamber for collecting the fine particles classified in said fine particle classifying chamber onto a substrate as well as for collecting the transparent medium generated by said transparent medium generating means onto said substrate and for depositing said classified fine particles and said transparent medium onto said substrate,
• wherein the apparatus has an ultra-fine particle classifier including:
• a plurality of disks, arranged concentrically in parallel to each other, for defining therebetween a multi-stage classifying region for classifying the ultra-fine particles;
• slits, formed on said disks, for introducing a carrier gas and the ultra-fine particles into a subsequent stage classifying region through each of the disks,
• a sheath gas exhaust vent, provided at an axis portion of each disk, for exhausting the sheath gas flowing from a periphery of each disk into each classifying region, and
• a carrier gas exhaust vent, provided on a lower portion of the last stage disk, for exhausting a carrier gas and classified ultra-fine particles,
• said ultra-fine particle classifier classifying charged ultra-fine particles in said classifying regions.
