The deoiled asphalt as the carbon source and the ferrocene as the metal source and the catalyst precursor were chosen to synthesize iron-containing carbon microparticles through co-carbonization at the temperature of about 450℃ for 3 h. The resulting products were treated at 2 000 ℃ for 2 h. All samples were examined by high resolution transmission electron microscopy （HRTEM） and X-ray diffraction （XRD）. The results show that the iron particles in the heat-treated material are completely coated by carbon. In addition to the fully filled carbon microparticles as well as hollow carbon ones, also form carbon fibers with hollow centers. The formation mechanism of the as-prepared products was discussed briefly.

An insert layer structure organic electroluminescent device（OLED） based on a new luminescent material （Zn（salen）） is fabricated. The configuration of the device is ITO/CuPc/NPD/Zn（salen）/Liq/LiF/A1/CuPc/NPD/Zn（salen）/Liq/LiF/A1. Effective insert electrode layers comprising LiF（1nm）/Al（5 nm） are used as a single semitransparent mirror, and bilayer cathode LiF（1 nm）/A1（100 nm） is used as a reflecting mirror. The two mirrors form a Fabry-Perot microcavity and two emissive units. The maximum brightness and luminous efficiency reach 674 cd/m^2 and 2.652 cd/A, respectively, which are 2.1 and 3.7 times higher than the conventional device, respectively. The superior brightness and luminous efficiency over conventional single-unit devices are attributed to microcavity effect.

Onion-like Fullerenes were produced at high-temperature in vacuum. The morphology of the carbon nano onion-like fullerenes was examined and characterized by high-resolution transmission electron microscopy (HRTEM). It can be seen that the nano-sized, onion-like fullerenes possess high degree of graphization. The results suggested that the catalyst is the main factor affecting the size and yield of the fullerenes. The method is very promising for simple mass production.

以三氧化铬(CrO3)与石墨为原料,利用真空热处理方法制备了三氧化二铬(Cr2O3)-石墨的插层化合物(GICs)。运用X射线衍射(XRD)分析石墨插层化合物。结果表明:经热处理后,在1400℃时CrO3与石墨(石墨∶CrO3=1∶1)与形成了纯5阶的石墨的插层化合物。XRD分析表明,对网状层面结构的天然石墨,可以利用真空热处理的方法使一些非碳反应物(Cr2O3)插入石墨层间,从而改变石墨的层面结构。X射线光电子能谱(XPS)分析和表征了Cr离子以3价的形式存在于石墨插层化合物中。
