摘要

Carbon Dots (CDs) are a class of zero-dimensional materials that are considered as the latest addition to the fluorescent family with potential applications in various fields owing to their immense chemical, biological, and physical properties. Although there is increasing interest in the synthesis of highly luminous CDs from biomass and fruits, the use of dangerous chemicals raises severe concerns. Therefore, our goal is to create CDs utilising Moringa leaves without the use of any dangerous chemicals. CDs can be used as reducing agents with good results, however, there aren’t many studies on the subject, which is a major drawback. To verify the reducing power of CDs (MCDs) generated from Moringa leaves, we have carried out the reduction of graphene oxide with the synthesized MCDs. Fluorescent gels based on CDs have emerged as a new class of material with potential applications in bioimaging, photonics, and sensing. CD-based fluorescent gels are made by simply adding CDs into the pre-synthesized gels; hence, we have tried the fabrication of fluorescent gels using MCDs and the triblock copolymer. Thus, prepared gels are added into the polyvinylidene difluoride (PVDF) matrix as a filler to make smart composite films with shape memory characteristics. Hence, this study also intends to create shape memory fluorescent films using CDs for the first time, which will be useful in the domains of biomedicine and anti-counterfeiting.
