Abstract

Abstract: Carbon dots are an emerging class of zero-dimensional carbon nano-optical materials that are shining in many fields. Compared with visible light, near-infrared light has deeper tissue penetration and lower scattering and has obvious advantages in fields such as biological imaging. With the exploration of scientific researchers, the regulation of the luminescence band gap of carbon dots has been continuously red-shifted from the initial blue-violet light to longer wavelengths. In recent years, carbon dots with near-infrared absorption/emission have been gradually reported. Based on a series of work of this research group in the near-infrared carbon dots, this review summarizes and reviews the latest progress in preparation strategies and applications of near-infrared carbon dots and prospected the future development directions.

Key words: Carbon dots, near-infrared, bioimaging, photothermal therapy, photodynamic therapy
