项目摘要

1) Fullerene films are processed by using plasma reactions in a small glass chamber, where a parallel-plates-type RF plasma is produced (13.56 MHz, 500 W).2) CィイD260ィエD2 film is well fluorinated by means of CFィイD24ィエD2 gas. By controlling gas pressure, input power and cooling of a substrate, fluorinated fullerene film including CィイD260ィエD2FィイD260ィエD2 is synthesized. Synthesis of CィイD260ィエD2FィイD260ィエD2 is not previously reported elsewhere. This fluorinated film has strong mass peaks around CィイD260ィエD2FィイD230ィエD2 - CィイD260ィエD2FィイD246ィエD2. As the fullerene film is damaged by the strong plasma iradiataion, plasma condition should be well controlled.3) CィイD260ィエD2 film is well oxidized by a oxygen-gas plasma. Oxygen molecules are well trapped between CィイD260ィエD2 molecules and they are weakly ionized.4) Fullerene film is oxidized by oxygen-gas plasma and its photo-electric property is measured by attaching electrodes. Under 3000 Lux of lamp light, electric conductivity of the film 1000 times increases compared with dark condition. As the oxygen molecules in the film is very stable in the air condition, this oxidized CィイD260ィエD2 film can be used as a photo-electric switch.5) Oxidized fullerene film is produced on a silicon wafer and its optical property is measured. As a results, it is found that this has photovolatic ability (solar cell). The quantum transferring efficiency is about 1%. Increase of the quantum transferring efficiency and photovolatic generation efficiency are tried by using transparent electrodes and by controlling the film thickness.6) CィイD260ィエD2 polymer (m[CィイD260-2nィエD2], m= 2-6) is successfully synthesized by using a laser desorption method. Synthesis of large CィイD260ィエD2 polymers is under investigation.

1)利用等离子体反应在一个小的玻璃室中处理富勒烯薄膜，在该玻璃室中产生平行板型射频等离子体（13.56 MHz, 500 W）。通过控制气体压力、输入功率和基片冷却，合成了含C γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ。C γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ。该氟化膜在C‑‑D260‑D2F‑D230‑D2F‑D2F‑D260‑D2F‑D246‑D2F‑D2附近有很强的质量峰。由于强等离子体辐射会破坏富勒烯薄膜，因此需要控制好等离子体条件。3) C γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ。氧分子被很好地捕获在C γ γ γ D260 γ γ γ D2分子之间，它们被弱电离。4)利用氧气等离子体氧化富勒烯薄膜，并通过贴附电极测量其光电性能。在3000lux的灯光照下，薄膜的电导率比黑暗条件下提高1000倍。由于膜中的氧分子在空气条件下非常稳定，因此这种氧化的C‑‑D260‑‑D2膜可以用作光电开关。5)在硅片上制备氧化富勒烯薄膜，并测量其光学性能。结果发现，这种具有光伏发电能力（太阳能电池）。量子转移效率约为1%。通过使用透明电极和控制薄膜厚度，尝试提高量子转移效率和光伏发电效率。6)采用激光解吸法成功合成了C γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ γ。目前正在研究大尺寸C‑C‑D260‑C‑r‑D2聚合物的合成。
