摘要
本文合成出了系列样品Sb_xBi_(2-x)Ti_4O_(11),得到了它们在常温常压下的拉曼光谱。实验结果发现:体系在x=0.4和1.2处经历了两次相转变,且相变与“软模”随Sb^(+3)的浓度变化有关。
The mixed system Sb_xBi_(2-x)Ti_4O_(11) has been synthetized and the Ra- man spectra measured at ambient temperature and pressure. The experimental results reveal that the mixed systems undergoes two times phase transitions, one of which concern with the concentration of Sb^(+3)ions dependece of the soft mode.
