description | [Image: see text] A simple procedure of producing three-dimensional blisters of graphene through irradiation of the visible range laser by Raman spectrometer has been presented. Fabrication of different volumes of the blisters and their characterization were carried out with Raman spectroscopy by tuning the irradiation dose. The produced blisters showed a consistency in altitude and a remarkable change in functionality, adhesion force map and local contact potential difference as compared to untreated monolayer graphene and naturally occurred graphene nanobubbles. Nevertheless, bilayer graphene is unaffected in the applied laser doses. The laser irradiation led to lattice expansion of carbon atoms and introduced oxygenic functional groups with the structural disorder. The internal pressure of the gaseous molecules was evaluated by monitoring the shape of the graphene blisters and nanobubbles. High-resolution Raman mapping showed the impact of laser-affected area and the defect density (n(d)) is reported as a function of displacement. Our results reveal ease of applicability of the Raman laser for the imaging and texturing of graphene pointing toward the possibility of the desirable and cost-effective laser writing at the submicron scale by tuning photochemistry of graphene which is pivotal for numerous applications. |
