Research field

I am exploring upconversion materials. Upconversion luminescence is the emission of high frequency radiation from a system excited with radiation of a lower frequency. It is a common phenomenon among the lanthanides but it is rare in transition metal systems. Therefore the search for new d-metall upconversion materials and their spectroscopic characterization provides a challenging task for my PhD thesis.
