摘要: 用固相反应法制得α-LiAlO2样品,并首次得到该材料的Raman光谱.Raman光谱表明,在654cm-1和426cm-1处存在两个较强的Raman光谱峰,分别对应于A1g和Eg振动模式.与α-LiCoO2比较可知,α-LiAlO2的层间结合力相对于α-LiCoO2更弱,其层状属性更强.

关键词: &alpha, -LiAlO2, Raman光谱, 振动模式

Abstract: We have for the first time measured Raman spectrum from a solid state synthesized LiAlO2. There are two Raman bands located at 654 cm-1 and 426 cm-1, which corresponds to A1g and Eg models, respectively. The interaction between the layers along c axis in α-LiAlO2 is weaker than that in α-LiCoO2. The characteristics of a layer compounds in α-LiAlO2 is stronger.

Key words: α-LiAlO2, Raman spectrum, Vibrational mode
