Hydrothermal synthesis of carbon quantum dots and study of its photoluminecence property

Different carbon nanostructures have attracted the fascination of the researchers due to their possible application in optoelectronic and bioimaging applications. In this work, the synthesis of water soluble carbon quantum dots (CQD) is reported. The quantum dots are produced by a simple hydrothermal technique followed by centrifugation process. The structures of the prepared carbon dots were studied by field emission scanning electron microscope (FESEM) and high resolution transmission electron microscope (HRTEM). The photoluminescence property of the as prepared sample was studied in details.
