Quantum dots (QDs) have been applied to many research fields due to their good photoelectrochemical properties and photostability. For preparation QDs, cadmium chalcogenide (CdS, CdTe, CdSe, and etc.), the IV semiconductor, have been generally employed because of their easy size tunable process, optical properties and r excellent photoelctrochemical responses. However, due to their inherent toxicity, there are some restrictions in applying these materials for bio-systems. In the present work, less toxic quantum dots, Cu2O QDs were prepared in apoferritin cavities by one-pot process. For investigating their morphology and crystalline, HR-TEM and XRD were employed. The size of synthesized Cu2O QDs was around 3 nm and XRD pattern clearly showed the crystalline Cu2O peaks. In addition, the photoluminescence (PL) and absorbance were measured for evaluating their optical properties. In PL emission spectra, a sharp maximum peak was observed at 410 nm. |
