Scattering by core-shell semiconductor microinclusions for plasmonically enhanced near-IR applications

We computationally design highly reflective, plasmonically enhanced coatings for more sensitive and versatile radiation detectors in the infrared regime. The large scattering crosssections of microinclusions are exploited to design devices and spectrally sensitive coatings for sensors, high temperature insulators, and solar applications. We focus on coreshell microinclusions composed of silver or low-bandgap semiconductor which have plasmonic resonances with excellent and tunable scattering properties without suffering from losses at high temperatures. These particles display a rich spectral response dependent on the complex refractive index of the particles.
