摘要： Disclosed is a technique of producing that a technique of producing quantum dots that are nano-size semiconducting crystals. An apparatus of producing quantum dots includes a mixer to mix different kinds of precursor solutions uniformly in a channel by diverging each precursor solution into a plurality of micro streams and joining the diverging micro streams individually with different kinds of micro streams, and a heating furnace to pass the precursor mixture solution discharged from the mixer therethrough to create and grow quantum dot nucleuses, thus producing quantum dots. The mixer may further include a heating unit allowing temperature adjustment. In addition, a buffer which is maintained at a relatively low-temperature is provided between the mixer and the heating furnace in order to prevent additional nucleation. Accordingly, quantum dots may be produced even at a high flow rate, which leads to mass-production of quantum dots.

摘要： Disclosed is a technology of producing quantum dots that are nano-size semiconducting crystals. A quantum dot producing apparatus includes a mixer for mixing precursor solutions, and a heating furnace with a plurality of heating areas providing different temperature conditions to heat the precursor mixture. Between the heating areas, a buffer may be installed which provides a low-temperature condition to prevent addition nucleation. Through this configuration, nucleation is separated from nuclear growth, uniformity in particle size of quantum dots is improved, which enables the mass-production of quantum dots, rather than a quantum dot producing apparatus with a single heating area that provides a constant temperature condition.
