Abstract

Abstract: Carbon dots are class of carbon based zero dimensional materials having immense biological, chemical and physical properties due to their tuneable fluorescence and attractive physicochemical properties. Blue fluorescence emitting carbon dots were synthesized by following a green route from the carbonized Lawsonia leaves. The green synthesized carbon dots were characterized using UV visible and luminescent spectroscopy and the surface morphology was monitored using High resolution transmission electron microscopy. The carbon dots were doped with Fe 2+ and the effect of doping on the fluorescence emission was also analysed.
