“…[34]. Also, rGO have been obtained employing various types of irradiation such as microwave [35,36], far infrared [37], pulsed laser [38,39] irradiation, UV [40,41] and visible [42] light. Besides the green environmental approach, these techniques have the advantage of gradual, controllable reduction of graphene oxide films and suspensions to a desired level and, in case of light assisted reduction, masking/treating of selected areas for manufacture of flexible electronic devices.…”
