Abstract： The Raman scattering in Zn0.74Cd0.26Se/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 (LOb) and the Zn0.74Cd0.26Se-like LO-phonon (LOw) have been obtained. At 2.7GPa, the pressure-coefficients of both LOb and LOw phonon energies increase abruptly The 2LOw-phonon resonance has been observed at 1.82GPa with 488.0nm excitation for the Zn0.75Cd0.25Se/ZnSe superlattices.
