英文摘要	通过将不同直径的ZnO纳米颗粒与碳纳米管连接制备了碳纳米管/ZnO纳米复合体.将团聚的ZnO纳米颗粒分散并用表面活性剂CTAB使纳米颗粒带正电.化学氧化碳纳米管使其带负电.ZnO/CTAB微团通过碳管表面羧基与CTAB的静电作用与碳纳米管连接形成纳米复合体.研究了复合体形成的不同实验条件,表征了碳纳米管/ZnO纳米复合体的结构并研究了纳米复合体的光学特性.研究表明,与碳纳米管连接的ZnO纳米颗粒是互不连接的并保持量子点的特性.光致发光研究表明ZnO纳米颗粒的激发在纳米复合体中有淬灭.; A CNT/ZnO nanocomplex was fabricated by attaching ZnO nanoparticles with various diameters to carbon nanotubes (CNTs). The as-prepared agglomerate ZnO nanoparticles were dispersed and positively charged by utilizing a cationic surfactant cetyltrimethyl ammonium bromide (CTAB). ZnO/CTAB micelles were subsequently anchored to the surface of CNTs by electrostatic interaction between carboxyl groups on the chemically oxidized nanotubes' sidewalls and CTAB molecules. Different experimental conditions for the attachment were studied. The CNT/ZnO nanocomplex was characterized using structural and optical analysis methods. ZnO nanoparticles attached to the carbon nanotubes were found to be separated from each other maintaining characteristics of quantum dots Photoluminescence study showed that the emission of ZnO nanoparticles was quenched in the nanocomplex.; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 02; 145-151; 23
