Abstract

Green chemistry of fluorescent carbon nanoparticles (CNPs) from common sources such as leaves has gained significant interest due to their strong optical properties, and high photo stability. This paper highlights a microwave-assisted approach for the synthesis of carbon nanoparticles from the leaf extract of two plants Syzygium Cumini and Ocimum tenuiflorum, (commonly known as Jamun and Tulsi, so addressed here as JNPs and TNPs respectively), possessing various natural medicinal benefits, being addressed here as JNPs and TNPs. They exhibited an average size of 70 nm and emitted red fluorescence when exposed to ultraviolet light. The absorption spectra of both were recorded, alongside investigating functional groups using Fourier transform infrared spectroscopy. The average crystallite size for TNPs and JNPs is 23.63 nm and 28.35 nm were recorded using X-ray diffraction (XRD). Due to their excellent fluorescent property, they can be potentially used for drug delivery and therapy applications, thereby replacing the usage of conventional organic fluorescent molecules/dyes.
