From: Plasmonically Enhanced Reflectance of Heat Radiation from Low-Bandgap Semiconductor Microinclusions
Effect of an increase in the refractive index of the host medium on the optical spectra of the microcomposites due to plasmonic resonances. (a,b) Spectral reflectance and (c,d) absorbance for microcomposites with a volume fraction f = 0.01 of (a,c) Si and (b,d) Te particles of different sizes d embedded in a dielectric medium of refractive index n m = 1.5 and 1.3. (e) An expanded view of the reflectance peaks for composites with Si microinclusions shown in (b). A clear redshift in the reflectance peaks is observed with an increase in the refractive index of the host medium pointing to the generation of LSPRs in the larger semiconductor microinclusions.
