中文摘要
在本研究中,我们以中空蛋白铁蛋白为模板,制备了圆偏振发光的硫化镉量子点。此外,我们还阐明了蛋白质向量子点的手性转移的机理。因此,我们在室温下以铁蛋白为模板,成功地将铁蛋白核心的手性转移到了硫化镉量子点的晶格结构上,成功地制备了圆偏振的硫化镉量子点。此外,我们还可以利用激光加工技术对圆偏振发光的发射波长进行调制。
英文摘要
In this study, we prepared circularly polarized luminescent CdS quantum dot by using hollow protein, ferritin, as a template for bio-mineralization. In addition, we elucidated mechanism of the chiral transfer from protein to quantum dots. As a result, we successfully prepared circularly polarized luminescent CdS quantum dots by using ferritin as a template at room temperature, in which chirality of the inner core of ferritin was efficiently transferred to the lattice structures of the CdS quantum dots. In addition, we could succeed in modulation of emission wavelength of the circularly polarized luminescence with laser fabrication technique.
