luminescence quenching meaning in English
发光猝灭
Examples
- But in the moderate electric field 150 kv / cm , there is a sharp change in the configuration and charge distribution of the exciton , i . e . the exciton is directly split into an electron polaron and a hole polaron . the polarization and dissociation happen at a same time , which differs from that in conjugated polymers . and in the strong electric field 350 kv / cm , appear structural phase transition of the chain and luminescence quenching
同时得到两个重要的临界电场值： 1激子解离电场ec1 （ 150kv / cm ） ，在此电场下激子发生瞬间解离，成为电子型极化子和空穴型极化子； 2结构相变电场ec2 （ 350kv / cm ） ，在ec2下二聚化晶格开始被等距晶格取代， ptcl络合物链发生结构相变，并伴随peierls能隙渐趋消失和发光猝灭的现象出现。 - The result showed that the spin coating method was better relatively . the obvious blue shift of pl was found in spectra of the ps / pmma composite prepared with spin coating . compared to the spectra from original ps sample , the luminescence quenching was greatly decreased for ps / pmma composite due to the prevention to ps layer with coated with pmma film and modification of dielectrical penetrability of the medium in quantum threads by the pmma
实验结果表明，用旋涂法实现的pmma固化后再与多孔硅复合而制得的样品的结果最好，它与原始的多孔硅样品相比发光峰发生了蓝移而且发光强度下降很小，我们认为pmma层有限的厚度和pmma对多孔硅表面的保护使复合后发光强度下降很小，而且制备的多孔硅pmma复合体系的发光强度几乎不随时间而下降。
