Paper Abstract

Harnessing more energy from the sun has led to the development of materials which can efficiently trap the sun radiation in the whole spectrum and re-emit it into a narrow spectral band corresponding to the band gap of a photovoltaic device. The field of metamaterials is largely aimed at designing nanostructured surfaces with tailored absorption (emission) spectra. Many rare-earth doped crystals and glasses can efficiently absorb light throughout the whole visible and near-infrared range of the spectrum and emit radiation at longer wavelengths (1.5 to 3 microns). We report studies of absorption and thermal emission of several rare-earth doped crystals.
