Research Interests
Our research focuses on the synthesis and applications of nanocrystals - in particular semiconductor nanocrystals or quantum dots.
The interest in nanocrystals stems from the fact that these tiny fragments of matter exhibit properties dependent on the size of
the crystals. Semiconductors offer the possibility of obtaining fluorescence owing to excitation decay across the band gap. The energy of
emission can be tuned by changing the size of the nanocrystals.
