以金刚烷溶解的超临界氙气为介质，在温度T=290.2 K、压力p=5.86 Mpa的条件下，用脉冲激光烧蚀高定向热解石墨(532 nm；52J/cm~2；7 ns；10 Hz)制备了纳米碳材料。产物的显微拉曼光谱表明，在钻石结构中也发现了具有SP3杂化键的碳氢化合物。用气相色谱-质谱法证实了金刚烷的合成。同样的测量还表明，可能合成了其他直至八烷烷的金刚烷类化合物。因此，超临界流体中的激光烧蚀被认为是一种合成类金刚石的实用方法。
Nanocarbon materials have been synthesized by pulsed laser ablation (532 nm; 52 J/cm2; 7 ns; 10 Hz) of highly oriented pyrolytic graphite in adamantane-dissolved supercritical xenon at a temperature T = 290.2 K and pressure p = 5.86 MPa. Micro-Raman spectroscopy of the products revealed the presence of hydrocarbons possessing sp3 hybridized bonds also found in diamond structures. The synthesis of diamantane was confirmed by gas chromatography-mass spectrometry. The same measurements also indicate the possible synthesis of other diamondoids up to octamantane. Thus, laser ablation in supercritical fluids is proposed as one practical method of synthesizing diamondoids.
