The first phase transition,from the rhombohedral to tetragonal phase,occurs at 34℃,corresponding to the disappearing of the soft A_1 mode and the mergence of the photoluminescence spectra.
观察到在不同温度下拉曼光谱的变化,经分析这些变化反映了该晶体经历了两个相变:第一个相变温度发生在34℃,软模的出现和荧光光谱的变化代表了三方相到四方相的转变;第二个相变温度发生在144℃,780cm~(-1)处模式在VH偏振下的消失标志了四方相到立方相的转变。
