Synthesis of Cu-In-S/ZnS Quantum Dots in the Aqueous Phase by Microwave Irradiation |
| 초록 |
Recently various nano materials have been prepared by using microwave irradiation (MW). Microwave irradiation generates rapid heating of polar substance and consequently results in faster, cleaner and more efficient reactions than conventional heating method. In this study, water soluble Cu-In-S/ZnS core/shell quantum dots (QDs) were successfully synthesized in the aqueous phase by MW. L-Asorbic acid and Trisodium citrate dehydrate were used stabilizer between indium and copper ions. The optical properties of the preparation QDs were characterized by photoluminescence spectroscopy and UV/Vis spectroscopy. The chemical structure of the QDs were characterized by XRD and Energy dipersive X-ray spectroscopy. With the increase ZnS shell size, PL peak of the QDs was red shifted. |
