Abstract

The paper reports sensing aspects of measurands by implementing the concept of surface plasmon resonance (SPR) that occurs at the metal-dielectric interface under proper incidence light conditions. For this purpose, the prism-coupled waveguide configuration is used. As to the metallic partner, nanolayers of silver and gold are taken into account, and the aqueous solutions of measurand with different concentrations are considered as the dielectric partner. As such, the set-up essentially uses the Turbadar-Kretschmann-Raether (TKR) kind of configuration to theoretically determine the concentration of sucrose solution. Moreover, the performance of sensors has been evaluated under the implementation of both silver as well as gold nanolayers through comparing the sensitivity in these situations. Theoretical investigations determine that the configuration with the use of gold becomes more sensitive as compared to the case when silver nanolayer remains in use.
