论文摘要
苯甲腈的冰壁架是一种芳香族，该芳族在星际培养基中已检测到氰化物侧链，受到真空紫外线光子辐照的影响，并发现形成残基。将残基从底物中取出，并将其放置在量化的边缘上进行电子显微镜分析。透射电子显微镜显示量子点（QD）和氮掺杂的石墨烯（N-石墨烯）。衍射和能量分散X射线光谱揭示了观察到的石墨烯片的结晶性质和碳氮组成。这是星际温度下冰辐射中QD和N-磷酸合成的第一个结果。
Icy mantles of benzonitrile, an aromatic with a cyanide side chain that has recently been detected in the interstellar medium, were subjected to vacuum ultraviolet photon irradiation and found to form a residue. The residue was removed from the substrate and placed on a Quantifoil grid for electron microscopy analysis. Transmission electron microscopy showed Quantum Dot (QD) and Nitrogen-doped Graphene (N-Graphene) sheets. Diffraction and Energy Dispersive X-ray Spectroscopy revealed the crystalline nature and carbon-nitrogen composition, of the observed graphene sheet. This is the first result showing QD and N-Graphene synthesis in ice irradiation at interstellar temperatures.
