Jun 25, 2025 · Materials emitting circularly polarized luminescence have seen a resurgence in research interest over recent years.

Here we demonstrate a high-sensitivity (noise level of the order of 10 -4), broadband (about 400-900 nm), transient (nanosecond resolution, millisecond range) full-Stokes (CPL and linear polarizations) …

To enable more-efficient electronic displays, Feldmann’s team is now trying to create LED materials that emit circularly polarized light, whose waves spiral like a left- or right-handed corkscrew.

Jan 12, 2025 · We demonstrate its broad applicability by measuring compounds with low dissymmetry factors across various timescales, as well as tracking the temporal evolution of linear polarization …
