Attosecond transient absorption spectroscopy (ATAS) is an advanced technique that enables the direct observation of electron dynamics on the attosecond (10⁻¹⁸ second) timescale. By utilising ...

This mechanism is supported by the following key experimental evidence: the phonon-assisted upconversion photoluminescence spectrum exhibits an anti-Stokes shift of 70 meV; the transient ...

Excess energy redistribution dynamics operating in nitrobenzene under hexane and isopropanol solvation were investigated using ultrafast transient absorption spectroscopy (TAS) with a 267 nm pump and ...

The nanoscale structural-photophysical heterogeneity in complex systems, including solar light-harvesting materials, often results in spectral overlaps of transient species and multiexponential ...
