Graphene oxide based SPR sensor for sensing of sea water concentration

Graphene oxide based SPR sensor for sensing of sea water concentration

In this paper, we demonstrate a graphene oxide (GO) based surface plasmon resonance (SPR) sensor for desalination of sea water. Gold layer is used as a plasmonic layer for the sensor. The thickness of gold layer is optimized at different wavelengths, i.e., 632.8 nm, 643.8 nm and 700 nm to achieve be...
