preparation example 1
[0255] Preparation Example 1: Quantum dot A with CdSe (core) / ZnS (shell) structure
[0256] CdO (0.4 mmol), zinc acetate (4 mmol), oleic acid (5.5 mL) and 1-octadecene (20 mL) were added to the reactor and reacted by heating to 150°C. After the reaction, the reaction mixture was placed under a vacuum of 100 mTorr for 20 minutes to remove acetic acid generated by displacement of oleic acid into the zinc.
[0257]After that, the reaction mixture was heated to 310° C. to obtain a transparent mixture, and the transparent mixture was kept at 310° C. for 20 minutes. Then, the Se and S solutions in which 0.4 mmol Se powder and 2.3 mmol S powder were dissolved in 3 mL trioctylphosphine were rapidly injected into the 2 and Zn(OA) 2 solution in the reactor. The resulting mixture was grown at 310°C for 5 min and then stopped in an ice bath.
[0258] Afterwards, after ethanol precipitation, the quantum dots were separated by centrifugation, and excess impurities were washed with chl...

[0259] Preparation example 2: Quantum dot B with InP (core) / ZnS (shell) structure
[0260] 0.2 mmol (0.058 g) of indium acetate, 0.6 mmol (0.15 g) of palmitic acid and 1-octadecene (10 mL) were added to the reactor and heated to 120°C under vacuum. After 1 hour, the atmosphere in the reactor was replaced with nitrogen. Then, after heating to 280° C., a mixed solution of 0.1 mmol (29 μL) tris(trimethylsilyl)phosphine (TMS3P) and 0.5 mL trioctylphosphine was quickly injected into the reactor and reacted for 20 minutes. The reaction solution was rapidly cooled to room temperature, acetone was added, and the mixture was centrifuged to obtain a precipitate. The precipitate was dispersed in toluene. The obtained InP semiconductor nanocrystal exhibits a UV absorption maximum wavelength of 560-590 nm.
[0261] 1.2 mmol (0.224 g) of zinc acetate, 2.4 mmol of oleic acid and 10 mL of trioctylamine were added to the reactor and heated to 120°C under vacuum. After 1 hour, the atmosph...

[0262] Preparation Example 3: Quantum Dot Dispersion A-1
[0263] 25.0 parts by weight of Quantum Dot A of Preparation Example 1, 6 parts by weight of Aji SpaPB-821 as a dispersant, and 69 parts by weight of propylene glycol monomethyl ether acetate as a solvent were mixed and dispersed in a bead mill for 12 hours to prepare quantum dot dispersion A-1.
