Very strong 2LO phonon Raman scattering has been observed with ZnCdSe well layers. It is ascribed to the strong outgoing resonant enhancement. For the first time, ZnSe like LO phonon confined in ZnSe barrier layers and ZnCdSe like LO phonon confined in well bayers are observed under the excitation of 457.9 nm line at room temperature and 77K, respectively. The origins of this two kinds of LO phonon are discussed.
