Abstract
Carbon quantum dots (C-dots) have attracted tremendous interest because of their advantageous characteristics of cost-effectiveness and fluorescent nature. In this study, we developed a simple, economical, and effective method for the green synthesis of fluorescent carbon quantum dots using low-cost hydrothermal treatment of Tartaric acid as a carbon source. The as-synthesized C-dots were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), UV–Vis absorption spectroscopy, Spectrofluorophotometry, Fourier transform infrared spectroscopy (FT-IR). The synthesized C-dots possess stable fluorescent properties, good, bio-compatibility, and high quantum yield. The C-dots are highly crystalline, with longitudinal dimensions of 3.128 ± 0.17 nm. The XRD and TEM analysis indicates that the synthesized C-dots have a nearly spherical morphology and narrow size distribution. The results suggest that the proposed C-dots could be utilized for photovoltaic cell, bioimaging, drug delivery, and biosensor applications.
