A Spectral-Temporal Decoupling Framework for the High-Fidelity Reconstruction of Low-SNR Transient Absorption Spectra.
Transient absorption spectroscopy (TAS) is a cornerstone for investigating dynamical mechanisms in quantum dots, photovoltaics, and photosynthesis. A primary challenge in the field is the development of high-sensitivity techniques capable of probing species in low-signal regimes, such as single-molecule detection, spat...
