A Kretschmann surface plasmon resonance setup was used to detect relative humidity changes. The used prism had a gold coating of 50-nm thickness, and then, it was additionally coated with graphene oxide (GO) to increase its sensitivity to relative humidity changes. GO can adsorb moisture from air, i...
