• High efficient IR to UV-blue up-conversion in rare-earth doped nano-glass-ceramics.
• Long wavelength harvesting of unused portions of solar irradiation.
• Enhanced spectral response of water-splitting semiconductor electrodes of a PEC cell.
The use of hydrogen to feed Fuel Cells emerges as an attractive renewable solution to meet the terawatt carbon-neutral energy demand challenge. Rare-earth doped nano-glass-ceramics, presenting outstanding high intense UV-blue up-conversion processes, appear as an interesting approach to assist long wavelength light harvesting of solar irradiation, extending the photo-catalytic response to the red and near-infrared region to overcome the drawback of large band-gap materials used in the splitting of water into oxygen and hydrogen in a photo-electrochemical cell.
