Please join Yale Chemistry for a Silliman Seminar in inorganic chemistry with Prof. Gaël Ung, Associate Professor of Chemistry from University of Connecticut.

Summary: Circularly polarized luminescence (CPL) is the emission of light with preferential right- or left-polarization states (~chiral light). CPL has emerged as a next-generation light source since the added chiral optical information presents unique opportunities to enhance optical displays, bio-imaging, security features for banknotes and identification documents, and quantum networks. CPL spectroscopy is also a unique tool to study the fundamental electronic structure of excited states. We will show that a combination of synthetic and spectroscopic work on 4f and 5f elements can unlock some of those promising applications.
