報告摘要：
The surface plasmon resonance (SPR) imaging technique is well known as a label-free visualization method to characterize the near-field fluidic transport properties within a few nanometers from the surface with the use of excitation of surface plasmons by evanescent waves at the interface between metal and dielectric material. The key idea is that the SPR reflectance changes with the near-field refractive index (RI), depending on the variation of scalar properties, e.g., concentration and temperature, during phase change. In this talk, I will first briefly explain the fundamentals of surface plasmon polaritons (SPPs), surface plasmon resonance (SPR), and SPR imaging systems. Next, the present talk discusses the applications of SPR imaging to phase change phenomena: in-situ visualization during condensation and frosting processes, vapor accumulation between multiple droplets, and concentration changes during selective evaporation of binary mixture droplets.
