Fig. 4: TA spectra and kinetic traces.
From: Optoelectronic properties and ultrafast carrier dynamics of copper iodide thin films
a 2D color plot of TA spectra of as-grown CuI thin film under the pump excitation with λp = 320 nm and \({F}_{p}=0.64{{{{{\rm{mJ}}}}}}/{{{{{{\rm{cm}}}}}}}^{2}\). The corresponding absorption (black line) spectrum is also shown for comparison. b Kinetic traces in the first 1 ns at selected wavelengths. Inset: kinetic at 406 nm zoomed-in with time delay in the range of 15–35 ps. All the spectra are for the as-grown CuI thin film.
