Abstract

Photothermal properties of semiconductor materials have been widely studied in recent years, while the chirality-related photothermal properties of semiconductor quantum dots remain unclear. In this work, the photothermal conversion properties of l/d-Cys–Cu_2−x S quantum dots under 808 nm-wavelength laser irradiation were studied. Our studies showed the photothermal conversion performance of d-Cys–Cu_2−x S quantum dots to be obviously better than that of l-Cys–Cu_2−x S quantum dots. They also showed the main copper component of the l-Cys–Cu_2−x S quantum dot to be Cu(ii), and the content of Cu(i) in the d-Cys–Cu_2−x S quantum dot to be higher than that in the l-Cys–Cu_2−x S quantum dot. Raman measurements were taken to provide a meahanism for this photothermal conversion and indicated the involvement of local surface plasmon resonance (LSPR).
