| 摘 要： | 利用Raman光谱仪研究了我公司用高温高压合成的不同品种立方氮化硼(CBN)晶体。结果表明不同品种CBN晶体的Raman光谱有明显差别,可分为以下几种类型:(1)典型的CBN拉曼光谱,只有两个对应CBNTo和Lo模的Raman峰,分别位于1055cm-1和1305cm-1左右;(2)除了CBN的特征峰外,在925cm-1、955cm-1和1245cm-1左右出现额外峰;(3)有CBNTo模的峰,但对应于Lo模的峰消失,在1286cm-1左右出现一个不对称的宽峰。另外在760cm-1、920cm-1和1015cm-1处出现多个额外峰。(4)在1286cm-1左右出现一个峰形不对称的宽峰,对应To模的峰有较大的位移,Raman光谱中有强烈的从低波数端到高波数端呈上升趋势的背底。本文对产生这些Raman峰的原因进行了分析探讨。

| Abstract: | Different types of high-pressure,high-temperature synthetic cubic boron nitride(CBN) were studied using Raman spectra method.The results showed that the spectra of different types of CBN were significantly different,which could be classified as the following:(1) Only two peaks centering at 1 055 cm-1and 1 305 cm-1corresponding to the Lo modes of CBN crystal appeared,which was typical Raman spectra of CBN;(2)Additional peaks at 925 cm-1,955 cm-1and 1 245 cm-1could be detected beside the To and Lo modes;(3)Th... |
