摘要: The surface plasmon resonance of small metal particles is highly sensitive to the refractive index surrounding medium. However, for dispersed on a glass in polymer matrix, effective ill-defined. effects substrate and solvent indices individual gold nanoparticles (prisms decahedra) have therefore been investigated by dark field microscopy. It found that any given substrate, e.g., or quartz, band red-shifts when increased as expected. However sensitivity reduced from observed homogeneous medium, effect supporting matrix be great importance. dispersion relationship follows an equation form neff = (1 − α)nsub + αnmed where value α was vary 0.10 0.65 depending whether are embedded ...
