Figure 10

FESEM images and photocurrent curves of EPD coated GQDs and GQD solid sheet structures. The photographic and FESEM images of, (a) GQD interconnected solid sheets, (b) graphene quantum dots (GQDs), (c) GQDs decorated on solid sheets, (d–f) corresponding photocurrent curves of (a,b and c). The photocurrent measurements show an abrupt raise in the photocurrent upon GQD decoration on solid sheets.
