General description

Indium(III)oxide, also known as indium sesquioxide or In2O3. It is athermally stable compound, suitable for use in glass, optic, and ceramic applications.Indium oxide is also commonly doped with tin oxide (SnO2) to produce indium tinoxide (ITO), which is used in transparent thin conductive films for displays,energy-efficient windows, and photovoltaics. Indium oxide-based catalysts are alsoused in various catalytic applications including CO2 hydrogenation, directconversion of syngas into light olefins, and conversion of meso-epoxide intochiral β-amino alcohols.

Lanthanide Ions as Photon Managers for Solar Cells

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
