Application

Ytterbium(III) nitrate pentahydrate can be used as a precursor to synthesize:
  • Er–Mn: Yb3Al5O12 (YbAG) nanocrystals by nonaqueous sol–gel method. Yb3+–Mn2+ dimer sensitization significantly enhances the green upconversion emissions.
  • CaTiO3:Yb3+, Er3+ nanoparticles by coprecipitation method. These nanoparticles are used in the optical monitoring of mineralization and demineralization of bone scaffolds.
It can also be used as a dopant to prepare BiVO4 semiconductor photocatalysts with enhanced upconversion properties.

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).

The Rare Earth Crisis—The Supply/Demand Situation for 2010–2015

The rare earth elements impact nearly everyone in the world. All of the people living in advanced technological countries and almost all those living in third world countries utilize the rare earths in their everyday living—the car that one drives (gasoline is refined from oil using rare earth catalysts and catalytic converters reduce the polluting emissions from the automotive exhaust), watching the news on TV (the red and green colors in TV screens), the telephones and computers we use to communicate (the permanent magnets in speakers and disc drives), just to name a few examples.

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