From: Topological Luttinger-semimetal CoAs3 dye-sensitized photocatalyst for efficient solar hydrogen evolution

Fig. 3

Time slices of the TA spectra of a, b EY/CoAs3 composite and d, e pure EY solution under excitation at 570 nm. Comparison of the TA kinetic probed at different wavelengths in EY/CoAs3 (c) and EY (f). g Comparison of the TA kinetic probed at 420 nm between in EY solution (green), EY/CoAs3 (red), and EY/Bi2Se3 (blue). Solid lines are their tri-exponential decay fitting. Source data for Fig. 3 are provided as a Source data file.
