| Research Abstract |
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.
