Streszczenie

The Raman spectra of ferroelectric (CH3NH3)3Bi2Br9 single crystals were studied at temperatures from 80 to 300 K and in the wavenumber range 0–300 cm−1. A tentative assignment of the observed bands is proposed. The phase transitions reported at 188, 140 and 101.5 K influence the Raman spectra and the observed changes are discussed in terms of the possible mechanisms involved. The lowest phase transition at 101.5 K is directly connected with instability of the inorganic sublattice.
