摘要：

We report on the Raman spectra of CdIn2Se4 and ZnIn2Se4 obtained in a transparency region. These spectra have a disordered-like appearance at high frequencies. A comparison is made with the Raman and IR spectra of the similar compounds CdGa2Se4 and ZnGa2Se4. The overall vibrational behaviour is mainly determined by the anion and a correspondence may be observed between the frequencies of some high energy polar modes. A strong non-polar breathing mode is observed at nearly the same frequency in all these compounds. The observed similarities between the spectra are discussed within the frame of the existing simplified models.
