Abstract

Since their discovery in 2004, fluorescent carbon dots (C-dots) have been in increasing development with a wide range of applications. Since 2012, the use of carbon sources made from raw materials such as seeds, flowers, and others has increased, and the green synthesis of fluorescent carbon dots has increased. These C-dots have potential in several bioapplications due to their biocompatibility, stability, relatively low cost, biodegradability, nontoxicity, and environmental friendliness. This work discussed C-dot synthesis using different raw materials with different carbon sources and the main synthesis methods. The photophysical parameters of the fluorescence quantum yield () and fluorescent lifetime () are presented for green synthesized nitrogen-doped and undoped C-dots as important nanomaterial for environmental control. These carbon dot-based materials can be used to minimize waste in the textile industry and enhance their waste properties as possible antifungal and bactericidal agents for bioapplications. An overview of the different C-dots used for textile engineering applications and degrading dyes typically used in textile fabrics is presented.
