Optical investigation of reduced graphene oxide and reduced graphene oxide/CNTs grown via simple CVD method

Reduced graphene oxide-carbon nanotube (rGO-CNT) hybrid materials have been prepared via a simple CVD method. The photoluminescence (PL) properties of rGO-CNTs were investigated and compared with reduced graphene oxide. The results suggest that unlike rGO, rGO-CNTs possess a multicolor PL spectrum. Consequently, thanks to its unique optical properties, rGO-CNT can be a potential candidate in the fields of photonic and electronic materials.
