In this article, a D-shaped optical fiber refractive index (RI) sensor based on surface plasmon resonance effect is demonstrated. The extinction spectra of spherical gold nanoparticles suspended in a homogeneous media were measured and the results were adjusted with Mie's theory together with an appropriate modification of. Refractive index [ i ] n = 0.22722 Extinction coefficient [ i ] k = 3.0202 Wavelength, m n, k 0.5 1 1.5 2 0 2.5 5 7.5 10 12.5 15 RefractiveIndex.INFO Au (Gold) Yakubovsky et al. Increasing the refractive index from 1.00 to 1.60 results in an extinction peak shift of over 40 nm, moving the peak from the green to the red region of the spectrum. The refractive index determines how much the path of light is bent, or refracted, when entering a material.This is described by Snell's law of refraction, n 1 sin 1 = n 2 sin 2, where 1 and 2 are the angle of incidence and angle of refraction, respectively, of a ray crossing the interface between two media with refractive indices n 1 and n 2.The refractive indices also determine . Nano Letters 7 , 3418-3423 (2007). Be aware that the real part of the RI is . October 29, .
