Compared with their bulky or nanosized counterparts, nanostructured carbon materials attract many researchers due to their diverse practical applications. Graphene has been successfully fabricated using a pulsed laser ablation process. It relies on the exfoliation of a graphite disc to induce polycarbonate sheets suspended in an aqueous medium (deionized water). Chlorophyll was extracted from spinach and then mixed with graphene. The properties were studied using a scanning electron microscope (SEM) and X-ray diffraction (XRD). Various graphene nanostructures have been observed, such as disks, dots, and fibers. The optical properties were studied by UV-vis spectroscopy and photoluminescence (PL) measurements. PL of graphene typically shows strong photoemission in the visible region (400.7 nm, 675.3 nm).
