空穴对 meaning in English
hole pair
Examples
- Exciton is electron-hole pair held together by their mutual coulomb interaction .
激子就是由电子和空穴在相互间的库仑力作用下，相互维持在一起的电子--空穴对。 - The process of photoluminescence refers to the radioative recombination of electronhole pairs generated by shining high energy light on a crystal .
光致发光过程就是高能量光子照射到晶体上之后，晶体所产生的电子一空穴对的辐射复合过程。 - Xps showed that there were much chemical absorbing water on the ti _ ( 2 ) film surface which mainly existed in form of - oh , and the contents of - oh was increasing with the annealing temperature . hydrophilic property became better with the annealing temperature ; the essential relation between the changing of contact angle and light - induced - electrons and light - induced - cavities was studied in details . the photocatalysis of samples without heat treatment was very bad , but that of samples after heat treatment was much better
Xps的分析表明：试样的表面含有大量的化学吸附水，主要以羟基的形式存在，随着热处理温度的升高，吸附羟基的含量在增加；亲水性能测试表明：随着氧气分压的变化，其亲水性能变化不大，随着热处理温度的增加，试样的亲水性能在变好，并从理论上解释了亲水性能光照前后变化和光生电子?空穴对之间的本质关系。 - The negative photoconductivity effect was found in the dimixing phthalocyanine composites . the experiment results indicated that the negative photoconductivity effects were closely related with the partial charge transfer from the center metals to phthalocyanine rings , and the separation efficiency of photocarriers was a key factor to the photoconductivity
结果表明，共混复合后，其光电导性能表现出负效应，并发现酞菁中心金属与其相连的氮原子之间的部分电荷转移是引起复合体系光电导性能变化的根本原因，同时复合体系中的电子空穴对的分离效率是影响光电性能的一个重要因素。 - In addition , when the electron - cavity pairs migrates to the films surface , there is adequate water to react with these electron - cavity pairs in good time . this not only reduces the composition probability of the electron - cavity pairs but also produces a large number of highly active hydroxyls that enhances the photocatalytic ability
紫外光照射下产生的电子-空穴对迁移到薄膜表面后，有足够的水分子及时地与空穴发生反应，不但减少了电子-空穴的复合机率，而且产生大量的强活性羟基，使薄膜的光催化性增强。
