Studies on Nitrogen-dopped Carbon Nanodots

Abstract

Nitrogen-dopped carbon nanodots are emerging stars in carbon-based nanomaterials. Herein, we introduce our works on nitrogen-dopped nanodots, which were prepared through one-step microwave synthesis route. Our works demonstrated that the optical properties of the carbon nanodots can be modulated by nitrogen dopping concentrations and surface chemical environments, and realize carbon-nanodot-based fluorescent inks, ratiometric fluorescent nanosensor and optical pumped laser. Our studies aim at exploiting the luminescent mechanism of the nitrogen-dopped carbon nanodots, revealing the influencing factors on their luminescent quantum yields and their applications in bioimaging, sensing security, information storage, lasers and so on.
