A study of the Raman scattering in Zn_1-xMg_xSe (0 ≤ x ≤ 0.4) epilayers grown by molecular beam epitaxy on (100) GaAs and (111)_Zn ZnTe substrates has been performed. Two kinds of longitudinal optical phonon modes (LO_Zn-Se and LO_Mg-Se) were observed under excitation of the Ar⁺ and Kr⁺ laser lines at room temperature, whose frequencies and intensities depend characteristically on the Mg content.
