Abstract
The photoluminescence, photoreflectance and Raman spectra of ZnTe/Zn1-x Mn, Te superlattice samples grown by MBE technique were studied from 11 to 80K. Excitonic subband energy levels were calculated, in which the strain effec ts due to lattice mismatch were taken into account. The effects of conducti on band offset ratio Q(c,x) value and average lattice constant on the excit onic energy levels were discussed. Multi-phonon spectra lip to six-order ph onon overtone and the combination modes of optical phonons between wells an d barriers and in barriers were observed by Raman spectra.
