    Abstract: A quantum dot having a gradient shell structure and a method of manufacturing the same are provided to form economically the same within a short period of time by using a reaction difference of a semiconductor precursor. A quantum dot has a shell structure of a chemical compound of a second to sixth groups based on a chemical compound of a second to fourth groups. The chemical compound of the second to sixth groups for forming a shell has a band gap larger than a band gap of the chemical compound of the second to sixth groups for forming a core. The shell of the chemical compound of the second to sixth groups has gradient concentration. A method of manufacturing the quantum dot includes a process for mixing and heating the chemical compounds of the second group for forming the shell and the core, a process for heating the mixture at the temperature of 100-350 ‹C, a process for mixing the chemical compounds of the six group for forming the shell and the core, and a process for forming a shell structure having a gradient at the temperature of 100-350 ‹C.

    Abstract: A method for dispersing nanoparticles is provided to control array density of nanoparticles by adjusting pH of a charged nanoparticle dispersion, and thus form high-density nanoparticle single film without cohesion. A method for dispersing nanoparticles includes the steps of: (a) modifying the surfaces of nanoparticles to impart an electric charge to the surfaces of the nanoparticles; and (b) dispersing the surface-modified nanoparticles in a solvent and adjusting pH of the nanoparticle dispersion. A method for producing nanoparticle thin films comprises a step of arraying the pH-adjusted nanoparticle dispersion on a substrate by capillary force to prepare nanoparticle single film.
