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）通过在小玻璃室中使用血浆反应来处理富勒烯膜，在该玻璃室中产生平行型型RF血浆（13.56 MHz，500 w）.2）CII D260 D2膜通过CII D24 D24 D22气体的含量很好地荧光。通过控制气压，输入功率和基材的冷却，合成了包括CII D260 D2F D260 D2在内的氟化富勒烯膜。 CII D260 D2F260 D2的合成以前在其他地方没有报道。该氟化膜在CII D260 D2F230 D2 -CII D260 D2F246 D2附近具有强质量峰。由于富勒烯膜受到强等离子体iRadiataion的破坏，因此应很好地控制等离子体条件。3）CII D260 D2膜通过氧气血浆很好地氧化物。氧分子在CII D260E D2分子之间充分捕获，并且它们被弱离子化。4）富勒烯膜被氧气血浆氧化，其光电特性通过连接电气来测量。与深色状态相比，在3000升的灯光下，膜的电导率增加了1000倍。由于膜中的氧分子在空气条件下非常稳定，因此该氧化物CII D260E D2膜可用作光电开关。5）氧化富勒烯薄膜是在硅摇动上产生的，其光学特性是测量的。结果，发现它具有光变色能力（太阳能电池）。量子转移效率约为1％。通过使用透明电极并控制膜厚度，尝试了量子传递效率和光电发电效率的提高。6）CII D260E D2聚合物（M [CII D260-2NIE D2]，M = 2-6），使用激光欲次吸收方法成功合成。大型CII D260NIE D2聚合物的合成正在投资中。
