Fig. 3From: Plasmonic Sensor Based on Dielectric Nanoprisms a Spectral reflectance for an optimum design that uses AZO as the buffer layer as a function of the index of refraction of the medium under test. The sharpness of the resonance peak degrades as the index of refraction increases. b Sensitivity (left axis and black dashed line) and figure of merit (right axis and blue solid line) as a function of the index of refraction of the medium under testBack to article page
