Luminescence properties of solids

Recent advances have been made in research on the luminescence of solids. The areas which have received particular attention have been transition metal ion systems, upconversion systems, high-resolution spectroscopy and single molecule spectroscopy, scanning near-field optical microscopy, new scintillator materials and luminescence of silicon. The applied research is focused on opto-electronic applications of new luminescent materials. In addition, single molecule spectroscopy gives new insight into many fundamental aspects of physics and chemistry.
