(a) Transmission spectra of EtSH, en, and a binary EtSH-en solvent as well as a solution consisting of the binary solvent and Ge-Sb–Se-Te powder. (b) The time-dependent transmission spectra of the binary solvent. (c) The time-dependent transmission spectra of the solution. (d) The time-dependent ratio of the characteristic spectral signature at a wavelength of 7.9 µm (EtSH) to that at a wavelength of 7.4 µm (en).
