Abstract The Raman scattering in Zn_0.74Cd_0.26Se/ZnSe superlattices under hydrostatic pressures up to 4.53 GPa at room temperature has been studied. The pressure-dependences of the ZnSe-like LO-phonon (LO_b) and the Zn_0.74Cd_0.26Se-like LO-phonon (LO_w) have been obtained. At 2.7GPa, the pressure-coefficients of both LO_b and LO_w phonon energies increase abruptly The 2LO_w-phonon resonance has been observed at 1.82GPa with 488.0nm excitation for the Zn_0.75Cd_0.25Se/ZnSe superlattices.
