Graphene/PVA coated D-shaped fiber for sodium nitrate sensing

A graphene/Polyvinyl alcohol (PVA) coated D-shaped fiber structure for sensing sodium nitrate solutions is proposed in this paper. D-shaped single mode fiber (SMF) coated with graphene/PVA was used as a sensor for sodium nitrate liquid solutions with the concentration range of 1-7%. After monitoring...
