    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 doped quantum dots with magnetic and optical properties and a manufacturing method thereof are provided to obtain magnetic and optical properties by doping an element with a magnetic property in the quantum dot stably. A magnetic element-VI element precursor is synthesized by combining magnetic elements and VI group element. A II group element precursor is synthesized by heating the II group semiconductor element at a temperature of 100 to 300 degrees centigrade. A quantum doe is formed by synthesizing the magnetic element-VI element precursor and the VI group element precursor with the II group element precursor.
