摘要：

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 best possible sensing performance parameters like sensitivity, quality factor, and detection accuracy. The performance of the sensor with and without using graphene oxide is compared. Finally, it is observed that the higher sensitivity of proposed SPR sensor is about 3.33 times than that of a SPR sensor, without grapheme oxide.
