Absorption of light by a monolayer graphene-water complex

The optical properties of single-layer graphene-water complex with the help of powerful laser beam were investigated. According to the investigation an increase of light absorption by the sample was observed. Two possible causes of such anomalous absorption were considered: the doping process of single-layer graphene by the water molecules, and the scattering of optical radiation by microbubbles formed as a result of heating process of the monolayer. The obtained results demonstrated their simultaneous action.
