Bright‐Dark Exciton Splitting in Lead Iodide Perovskite Crystals Accessed via Quantum Beats in Photon Echoes

ABSTRACT Understanding the fine structure of excitons is crucial for optoelectronic and quantum photonic applications of lead halide perovskites. It is demonstrated that polarization‐sensitive photon echo spectroscopy in magnetic field provides a powerful method to access coheren...
