Abstract: A fabrication method of colloidal quantum dot nano-particle is provided to obtain the quantum dot having favorable concentration, particle size and bandgap energy without using expensive and toxic materials such as TOP or TOPO by adding bivalent anion type of sixth group metal(M2^2-) solution to second group metal(M1^2+) oleate. The method includes: first step of preparing second group metal oleate by reacting oleic acid in second group metal precursor solution of any one selected from Cd, Pb and Zn; second step of preparing a solution containing bivalance anionic sixth group metal by dissolving precursor of sixth group metal or cationic sixth group metal in a solvent with high boiling point of 200 to 350deg.C and proceeding reductive reaction of the solution at 100 to 200deg.C; and third step of producing colloidal quantum dot nano-particles by reacting the prepared oleate of second group metal and the prepared solution containing bivalance anionic sixth group metal at 100 to 250deg.C.
