APPARATUS FOR MANUFACTURING QUANTUM DOT WITH A PLURALITY OF HEATING ZONES AND METHOD FOR MANUFACTURING QUANTUM DOT

摘要

The present invention relates to a technology for manufacturing a quantum dot which is a semiconductor crystal of a nano size. The apparatus for manufacturing a quantum dot may be furnished with a mixer that mixes a precursor solution and a heating part that has a plurality of zones for heating the mixed precursor solution, the temperatures whereof are different from one another. Among said heating zones of different temperatures may be furnished buffers that block additional nucleus formation by low temperature. Uniformity of the particle size of quantum dots is improved by said structure and method, which separate nucleus formation from nucleus growth. In addition, the mass-production of quantum dots is made possible, in contrast with devices and methods that have a single heating zone of the same temperature.
