Effect of high pressure on as prepared 20mM CTAB capped CdS nanoparticles (size ~4nm) has been analyzed in this paper. Raman scattering has been used to observe the phase transition pressure. X-ray diffraction pattern is used for structural characterization. Raman scattering predicts the phase transition occur from mixed cubical phase to rock salt phase above 6.6 GPa. One of the representative XRD pattern at 9.7 GPa confirms the existence of rock salt phase above 6.6 GPa.
本文分析了高压对预先制备的 20mM CTAB 包裹的 CdS 纳米粒子（尺寸约为 4nm）的影响。拉曼散射用于观察相变压力。X 射线衍射图谱用于结构表征。拉曼散射预测相变发生在 6.6GPa 以上，从混合的立方相到岩盐相。在 9.7GPa 时的一个代表性 XRD 图谱证实了 6.6GPa 以上存在岩盐相。
