General description

Elemental sulfur exists in thirty different solid allotropes of which orthorhombic sulfur is the only thermodynamically stable form under normal temperature and pressure. It dissolves in a number of organic solvents and forms a large number of oxyacids. Sulfur is generally highly reactive; the S8 ring of elemental sulfur is easily broken by a number of nucleophilic reactants. The hydroxyl ions react with S at about 100oC.

Application

It finds applications in Li-S polymer batteries and as semiconductor-sensitizer layer CdS/CdSe/ZnS for solar cells.

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.
