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) 富勒烯薄膜通过在小玻璃室中使用等离子体反应进行处理，其中产生平行板型射频等离子体（13.56 MHz，500 W）。2) D2 薄膜通过 CF D24 D2 气体充分氟化。通过控制气压、输入功率和基底冷却，氟化富勒烯薄膜包括合成 C-D260-D2F-D260-D2 之前未在其他地方报道过该氟化膜在 C-D260 D2F D230 D2 - C D260 D2F D246 D2 附近具有强质量峰。作为富勒烯薄膜会被强等离子体辐射损坏，应控制好等离子体条件。3）C260D2薄膜被氧气等离子体很好地氧化。氧分子被很好地捕获在C260D2分子之间，并且它们被弱电离。4）富勒烯薄膜是经氧气等离子体氧化，在3000Lux灯下测量其光电性能。光照条件下，薄膜的电导率比黑暗条件下提高1000倍，由于薄膜中的氧分子在空气中非常稳定，因此这种氧化C260D2薄膜可以用作光电开关。 5）氧化富勒烯薄膜。其结果是，在硅晶片上制作并测量其光学特性，其具有光伏能力（太阳能电池），其量子传输效率提高了约1%。通过使用透明电极和控制薄膜厚度来测试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C260D2聚合物(m[C260-2N2D2],m=2-6)。大型 C260D2 聚合物的研究正在研究中。
