Abstract

Nano- and microparticles particles embedded in compact layers interact with light in diverse ways. We investigate the scattering by semiconductor, metal, or oxide particles to direct near-infrared light without excessive heating. Optical responses under irradiation by solar and blackbody emitters are calculated. Reflectance efficiency factors of over 80% are predicted in 200 μm thick compact layers with only 1% volume fraction. The computational results are validated with experiments and implemented in near-infrared sensing applications.
