Photoluminescence spectrum of an interacting two-dimensional electron gas at \nu=1 [PDF]
We report on the theoretical photoluminescence spectrum of the interacting two-dimensional electron gas at filling factor one (\nu=1). We considered a model similar to the one adopted to study the X-ray spectra of metals and solved it analytically using ...

Lanthanide Circularly Polarized Luminescence: Bases and Applications
AbstractLanthanide (III) luminescence is very characteristic: it is characterized by narrow emission bands, large Stokes shift, and a long excited state lifetime. Moreover, chiral lanthanide complexes can emit strongly circularly polarized light in a way that is almost precluded to purely organic molecules.

Heterocyclic [9]Helicenes Exhibiting Bright Circularly Polarized Luminescence [PDF]
AbstractWe describe a concise synthetic strategy for the preparation of heterocyclic [9]helicenes and a simple preparative‐scale protocol for the optical resolution of the resulting M‐ and P‐enantiomers. The helicenes were characterized by single‐crystal X‐ray diffraction along with a range of spectroscopic and computational techniques.

Tetraaza[7]-[15]helicenes Synthesized by Two-Step Strategy: Length-Controlled Chiral π-Systems Exhibiting Amplified Circularly Polarized Luminescence. [PDF]
A modular two‐step strategy provides tetraaza[n]helicenes (n = 7–15) as a homologous series with tunable photophysical and chiroptical properties. Extension beyond n = 11 induces pronounced through‐space π–π interactions, narrowing the energy gap and amplifying circularly polarized luminescence.
