摘要：

The 948 K ferroelectric phase transition of Bi4Ti3O12 single crystals has been studied by Raman scattering measurements in the temperature range between 293 and 958 K. The lowest mode at 28 cm(-1) shows remarkable softening as the temperature increases from room temperature. The peak frequencies of bands above 100 cm(-1) reveal no remarkable change.
