| Research Abstract |
ZnSe quantum dots were synthesized by a hot-soap method, and the mechanism of the ligand-dependent phase determination was studied by using the oreic acid and oleylamine as complex ligands for zinc acetate. In the case of high supersaturation during the nucleation, the stable zincblende type ZnSe appears, while the metastable wurtzite type ZnSe appears in the case of low supersaturation during the nucleation. During the crystal growth period, no phase transformation depending on the supersaturation level occurs. Thus, it was shown that the phase appeared was determined during the nucleation period, and the complex ligand controls the supersuturation level.
