1. A method for synthesizing a carbon network comprising:

a. dissolving carbon nanodots (CNDs) in a solvent to form a CND slurry;

b. casting the CND slurry onto a substrate;

c. drying the CND slurry on the substrate to form a CND film; and

d. irradiating the CND film with a light beam to convert at least a portion of the CND film into the carbon network comprising turbostratic graphene.
