Experimental Raman scattering study of mixed Ag x Ga x Ge 1− x Se 2 (0.167 ≤ x ≤ 0.333) single crystals is reported. The spectra transformation upon composition variation exhibits the two‐mode type of behavior, with lines of the end‐member compounds of the solid solution (AgGaSe 2 and GeSe 2 ) dominating in the spectra, whose relative intensities vary with composition.
