Data about: Photogeneration, relaxation and many-body effects of excitons and charge carriers in MoS₂, WS₂, and the Mo₀.₆W₀.₄S₂ alloy, probed by transient optical absorption spectroscopy.

The samples studied in this dataset are of MoS<sub style="color:black;">2</sub>, WS<sub style="color:black;">2</sub>, and the Mo<sub style="color:black;">0.6</sub>W<sub style="color:black;">0.4</sub>S<sub style="color:black;">2</sub> alloy. Transient absorption measurements are performed on these multilayered compounds. By varying the pump photon energies and pump photon fluences, we studied the generation and relaxation dynamics of the photogenerated charges and/or excitons. To understand the spectral dynamics in detail, fits are made to the obtained signal. The signal is probed in the visible region and the data set contains the relevant files.
