Chiral Cu <sub> 2− <i>x</i> </sub> S quantum dots and their near-infrared photothermal conversion properties

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<sub>2-<i>x</i></sub>S quantum dots under 808 nm-wavelength laser irradiation were studied. Our studies showed the photothermal conversion performance of D-Cys-Cu<sub>2-<i>x</i></sub>S quantum dots to be obviously better than that of L-Cys-Cu<sub>2-<i>x</i></sub>S quantum dots. They also showed the main copper component of the L-Cys-Cu<sub>2-<i>x</i></sub>S quantum dot to be Cu(II), and the content of Cu(I) in the D-Cys-Cu<sub>2-<i>x</i></sub>S quantum dot to be higher than that in the L-Cys-Cu<sub>2-<i>x</i></sub>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).

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<sub>2-<i>x</i></sub>S quantum dots under 808 nm-wavelength laser irradiation were studied. Our studies showed the photothermal conversion performance of D-Cys-Cu<sub>2-<i>x</i></sub>S quantum dots to be obviously better than that of L-Cys-Cu<sub>2-<i>x</i></sub>S quantum dots. They also showed the main copper component of the L-Cys-Cu<sub>2-<i>x</i></sub>S quantum dot to be Cu(II), and the content of Cu(I) in the D-Cys-Cu<sub>2-<i>x</i></sub>S quantum dot to be higher than that in the L-Cys-Cu<sub>2-<i>x</i></sub>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).
