Abstract

In the experiments of Mössbauer spectroscopy, transmission electron microscopy (TEM) and atomic force microscopy (AFM) the morphology and structurization of the carbon phase, the charge state of europium and the dynamic properties of europium bis-phthalocyanine pyrolysed derivatives, including the Debye temperature, were revealed. It was found that the pyrolysis of europium bis-pthalocyanine resulted in the amorphous carbon matrix and nanoscaled graphene clusters both forming turbostratic carbon phase. The europium ions in the charge state Eu3+/Eu2+ were detected. The data indicated that localization of Eu ions took place between layers of graphenes similar to graphite intercalation compounds. It was shown that an isomeric shift, linewidths and the magnitude of the resonant absorption are essential characteristics of structural transformations at the pyrolysis of rare earth bis-phthalocyanines.
欧罗巴二丁酸丁酸激光剂在碳纳米结构中的金属离子的定位和充电状态
通过Mössbauer光谱、透射电子显微镜(TEM)和原子力显微镜(AFM)等实验,揭示了碳相的形貌和结构、铕的电荷态以及铕-酞菁热解衍生物的动力学性质(包括德拜温度)。研究发现,在双酞菁铕的热解过程中,非晶态碳基体和纳米级石墨烯团簇均形成涡层碳相。检测了带电态Eu3+/Eu2+的铕离子。数据表明,Eu离子的定位发生在石墨烯层之间,类似于石墨插层化合物。结果表明,同分异构体位移、谱宽和共振吸收大小是稀土双酞菁热解过程中结构转变的基本特征。
