Nano - tiopc60r , 40nm / ctm / pc = l / 80 / 100 , s762 . 5nm = 0 . 533cm2 / u j ) ; thereby the single - layer nanoparticle tiopc / fluorinone - based azo composite photoreceptors were prepared and their photoconductive properties were briefly studied . in conclusion , two originalities can be outlined from this thesis : ( 1 ) by using 1 , 4 - dioxane as disperse solvent , stable and uniform composites of tiopc , azo , hydrzone and polymer matrix were prepared , and the single - layer photoreceptors were successively fabricated with these composites , the photoreceptors showed high and wide range photosensitivity from visible to near infrared spectral regions 综上所述，本论文主要有以下两个创新之处： （ ）采用两杂性的二氧六环做分散溶剂，成功地实现了酞警氧钛、绿丹蓝偶氮、茶苯晚以及聚合物介质组成的、多相多组分体系的稳定复合，从而制备出从可见光到近红外光区都具有高光敏性的宽频响单层复合光导体。

A review of the development of organic semiconductor composite photo - conductive materials and devices was followed by a proposal of the researching theme in this thesis . the effects of fabrication arts such as solvents , gradient , interfacial layer and configurations on the photoconductive properties of the single - layer chlorodiane blue azo / tiopc composite photoreceptors were systematically studied in chapter ii . the results showed that the solvent played a decisive role in the multiphase and multicomponent system composed of two photogeneration species ( chlorodiane blue azo and tiopc ) , a transporting material ( hydrozone ) and polymer binder ; 1 , 4 - dioxane , as an amphiphilic solvent can effectively disperse and stabilize such multiphase and multicomponent systems , the derived photoreceptors presented improved photoconductive properties superior to those of dual - layer counterparts and demonstrated the evident synergetic enhancement and complementary effects ( eg 结果表明：在由两种光生材料氯丹蓝偶氮和酞菁氧钛、传输材料萘苯腙以及聚合物介质组成的多相多组分复合体系中，分散溶剂是至关重要的因素，二氧六环作为典型的双亲性溶剂，有效地分散和稳定了该多相多组分复合体系，得到的复合单层光导体的光敏性在整体上优于双层光导体，复合材料在可见光和近红外光区分别表现出的偶氮和酞菁氧钛的光敏性(如azo / tiopc = 8 / 2 ， cgm / ctm / pc = 1 / 120 / 120时，具有明显的互补效应；在近红外光区明显高于酞菁氧钛与偶氮光敏性的线性加和，表现出协同增强正效应。

In the work , it was systemically studied that the effects of two suggested modifying ways on electrochemical characteristics of lithium metal electrode and its behaviors in lithium cell . finally , the action mechanisms of these two modifying ways were analyzed . through the study on pretreatment effects of different cyclic ether on lithium electrode , it was found that 1 , 4 - dioxane ( doa ) and 1 , 3 - dioxolane ( dol ) , both could form a favorable passivating sei film on lithium electrode surface through 研究不同环醚对锂电极的预处理作用发现, 1 , 4 -二氧六环( doa )和1 , 3 -二氧五环( dol )对金属锂电极的表面预处理均可以在金属锂表面形成一层良好的sei钝化膜,对锂金属电极起到了保护性作用,使锂电极具有较小的界面阻抗,有效地提高了金属锂电极的充放电循环效率,改善了锂金属电极在循环过程中的表面形貌;而doa和dol对金属锂电极的表面预处理,不会明显的影响锂电极的动力学性能。

However , after co - porphyrin is kept in 1 , 4 - dioxane for two weeks , excited by 488nm , it shows apparent reverse saturable absorption and enhanced optical limiting effect , which can be attributed to the absorption cross - section change of exicited state in co - porphyrin derived probably from the production of co ( iii ) - porphyrin due to oxidation of 62 on co ( ii ) - porphyrin 钴卟啉( co ( ) tpp )对457 . 9nm 、 514 . 5nm和488nm波长的光都具有限幅作用，并对457 . 9nm波长的光呈现明显的饱和吸收。放置半个月的样品在488nm波长光的作用下表现出明显的反饱和吸收，并且其光限幅特性在488nm处表现出增强效应。
