Abstract

Fluorescent patterning has attracted a great deal of attention owing to its potential applications in different areas in particular anti-counterfeiting technology. Fluorescent carbon dots (CDs) as a type of fluorescent dyes can be used in invisible patterning due to their remarkable optical properties. This study attempts to introduce green fluorescent CDs as a promising factor in textile coding. Accordingly, a new green source opted to prepare CDs using the hydrothermal approach. Moreover, toxicity assays were performed to prove the safety of these carbon-based nanoparticles for humanity. They were also conjugated with cotton fiber successfully. Therefore, these green prepared CDs are promising for security labeling in the textile industry.
