  1. This paper presents the effects of some features on the productivity of raw c60 materials, such as distance and approaching speed of electrodes, helium partial pressure and arc current etc. then we separate and purify the raw materials and obtain pure solid c60 of 99. 9 % and compare the purification efficiency and effect of different fluxion phase and fixed phase and discuss the effects of the experimental conditions, such as the depositing speed, the type of the substrate, the surface structure of the substrate and the temperature of the substrate. finally, we use xps, afm, ultraviolet, infrared and raman to analyze the component, structure and feature of the films qualitatively and quantitatively

    本文首先研究了氣分壓、弧電大小、電極間距以及電極推進速度等實驗條件對制備c _ ( 60 )粗品產率的影響;接著選用柱色譜法分離提純得到了純度大於99 . 9的c _ ( 60 )固體,比較了不同相和固定相的提純效率和效果;然後採用自己改進后的真空鍍機,利用電阻式加熱蒸鍍方法,得到了純c _ ( 60 )薄和不同摻雜比的銀摻雜薄;探討了沉積速率、襯底種類、襯底表面結構以及襯底溫度等實驗條件對薄結構的影響;最後通過xps , afm ,紫外,紅外,拉曼對薄的成分、結構和特性作了定性和半定量分析。
