| Abstract: | In this paper the Raman scattering and fluorescence spectra of asymmetric coupled Zn 1-xCd xSe/ZnSe quantum wells were investigated. We found that the quantum wells had a clear fluorescence peak. The limited optical patterns of low well and wide well in ZnCdSe well, and the couple pattern of phonon and plasma on the ZnSe/GaAs interface were found, which has been analyzed simply. |
