실험 절차

1.421 g of lead acetate trihydrate (or lead oxide (PbO)) and 5 ml oleic acid were added into a reaction vessel containing 20 ml diphenyl ether solution and heated to a temperature of about 150° C. for 30 min to form a lead oleate. After cooling to 60° C., this solution was mixed with 12 ml TOPSe (or TOPTe) stock solution to prepare injecting precursor. Reaction was carried out at various injecting and reaction temperatures. Also various molar ratio of lead oleate to TOPSe stock solutions were tested for injecting precursor to find the optimum conditions of reaction. Typically, injecting the precursor solution at 130° C. of 30 ml diphenylether solution and keeping the reaction temperature at 110° C. for 5 min yielded approximately 5 nm sphere PbSe quantum dots. For the synthesis of larger size (>10 nm) cubic shape PbSe dots, lower injecting temperatures (<110° C.) or second injection of additional precursors at about 30% the amount of that in the first injection after the nucleation have been used were used
