Abstract
Carbon quantum dots (CQDs), a novel class of zero-dimensional carbon nanostructures with diameters below 10 nm, have recently come into existence. The authors have synthesized and analyzed carbon-based quantum dots from aloe-vera, rice, and sugar. The characterization of these quantum dots is done via UV-visible spectrophotometer. The quantum dots that are made from chemicals are toxic and are harmful to both humans and animals. However, the carbon quantum dots (CQD) which they have synthesized in this research work are bio-compatible, less toxic, and have the property of high aqueous dispersibility. CQDs are being used in various fields of applications such as bio-imaging, medical diagnosis, bio-sensing, chemical sensing, photo catalysis, and photovoltaic devices. This study helps the scientific community to understand the nature of carbon quantum dots and gives a brief idea of suitable materials that create CQD.
