no-phonon transitions and transverse optical phonon replicas were clearly identified. Systematic studies based on Rutherford ion backscattering and X-ray diffraction were performed.Backscattering and channeling anomalous spectra was observed due to the strain of superlattice.Photoluminescence(PL)and X-ray rocking curve analysis of the sample indicated that a good crystalline quality and commensurate growth is essential to radiative recombination.The dependence of PL on the growth temperature were discussed.
