论文摘要
据报道，纯粹是从阿甘坦（Adamantane）纯粹从阿甘坦（Adamantane）的12 GPA压力的超湿（2-5 nm）纳米座的合成。拉曼光谱学研究了它们的结构特征。在Raman Spectra中检测到了大约1147、1245、1344和1456 cm-1的异常振动带，其中包含许多明显的最大值和1456 cm-1。该频带与CHX组的弯曲振动模式终止了纳米原子表面。在1344 cm-1处过度强烈的模式通过其与1328 cm-1钻石声子的耦合来解释。发现发现的拉曼带被认为用于明确识别来自阿甘坦烷和其他具有较高氢含量的碳氢化合物的Ultrasmall Nanodiamonds。此外，钻石表面上的极化CH键对环境条件敏感。这为使用Adamantane生产的钻石作为生物学，化学和医学的超纳米传感器打开了机会。
The synthesis of ultrasmall (2-5 nm) nanodiamonds purely from adamantane at pressure of 12 GPa is reported. Their structural features have been studied by Raman spectroscopy. The unusual vibration band containing a number of pronounced maxima at about 1147, 1245, 1344, and 1456 cm-1 was detected in Raman spectra. The band is confidently identified with the bending vibrational modes of CHx groups terminating the nanodiamonds surface. Excessively intense mode at 1344 cm-1 is explained by its coupling with the 1328 cm-1 diamond phonons. The Raman band found is proposed to be used for express recognition of ultrasmall nanodiamonds produced from adamantane and other hydrocarbons with a high hydrogen content. Moreover, polarized CH bonds on a diamond surface are sensitive to environmental conditions. This opens up opportunities for using the diamond produced from adamantane as ultrasmall nanosensors in biology, chemistry, and medicine
