| 摘 要： | 本文对非静水压淬火的 C_(60)样品进行了拉曼光谱研究。在14.8GPa 以上,C_(60)的1468cm~(-1)特征峰的频率和线宽保持不变,这是 fullerite 相己转变成“透明相”的拉曼光谱证据。在32GPa 以上,原 C_(60)的散射峰全部消失,只观察到两个新的弥散的弱散射峰。表明 C_(60)原子团簇已倒塌或严重畸变。

| Abstract: | The non—hydrostatic pressure—quenched C_(60) has been investigated by Ra- man scattering.Above 14.8 GPa,the frequency and widthof the characteristic peak (1468 cm~(-1)) of C_(60) remain constant,which is evident that C_(60) fullerite phase transforms into an“transparent phase”.Above 32 GPa,all Raman peaks of the starting C_(60) disap- peared and only two new diffuse and weak peaks were observed,which indicated that C_(60) molecules were collapsed or distorted. |
