Broadband transient full-Stokes luminescence spectroscopy.

ABSTRACT: Materials emitting circularly polarized light (CPL) are highly sought after for applications ranging from efficient displays to quantum information technologies^1-7. However, established methods for time-resolved CPL (TRCPL) characterization have notable limitations^8-17, generally requiring a compromise between sensitivity, accessible timescales and spectral information. This has limited the acquisition of in-depth photophysical insight necessary for materials development. 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) spectroscopy setup. The achieved combination of high-sensitivity, broad wavelength respon
