By comparable investigation , two luminescence mechanisms can explain the different variety of pl intensity of origin and annealed samples and are dominant mechanisms separately in unanneal and anneal course 经过退火处理后，在相同波长的光激发下发光强度逐渐增强，峰型逐渐变好，发光谱带的半峰宽也变窄。

Our figures manifest that : ( 1 ) the quantity of the chlorophyll ' s fm has a transcient reduce and subsuquent increase behavor in the recovry while that of fem of membrance proteins excited at 278nm and 295nm show an direct increase in this process 结果显示: ( l )光抑制后直接弱光放置不同时间，叶片的叶绿素荧光强度先减少后增大，类囊体膜蛋白278nm和295nm光激发的荧光强度却先增大后减少再增大。
Green fluorescent protein ( gfp ) was extracted from jellyfish ( aequerea victoria ) of ocean invertebrate . gfp can emit green fluorescent when it is illuminated by light of suitable wavelength . the emissions of fluorescence need not any additional factors , such as substrate , supplementary factor 绿色荧光蛋白( greenfluorescentprotein ， gfp )是来源于多管水母( aequoreavictoria )等海洋无脊椎动物的一种蛋白质，该蛋白质在体外经适当波长的光激发便发出绿色荧光，并且这种荧光的发射不需要任何底物和辅助因子的诱导。
Excited with 228nm , the emission bands centered at about 365nm and 460nm originate from the electron transitions of 1d2 - 1s0 and 3d - 1s0 in ag + respectively , and the emission band at 400nm results from the surface plasma resonance of the silver nanoparticles , which aggregated near the surface of the films 在228nm光激发下，复合膜中ag ~ +的电子的~ 1d _ 2 ~ 1s _ 0跃迁和~ 3d ~ 1s _ 0跃迁分别在365和460nm附近发光，聚集在复合膜表面的纳米银粒子的表面等离激元共振导致了400nm附近的发光。
In addition , the breakdown and the degeneration of pcss " s are serious problems in the applications . in this dissertation the mode of luminous charge domain is perfected ulteriorly by deeply studying the dynamics characteristic of high - field domain of the trans - electron device with experiment stability of nonlinear pcss 本文在通过对转移电子器件偶极畴的动力学特征作了深入分析的基础上，结合非线性pcss ' s的稳定性实验，对非线性pcss ' s的光激发电荷畴理论模型作了进一步的完善。
It must be noted here that blue stimulated luminescence from polymineral fine grains presumably originate from both quartz and feldspar grains , and it is thus likely that any blue stimulated signal following an ir exposure in our samples will be richer in quartz osl in comparison to a pure blue stimulated signal without ir exposure Blsl信号由两部分组成，一部分既可以被蓝光激发，也可以被ir激发，另一部分只能被蓝光激发，这两种类型的陷阱在不同的预热温度中分布不均匀。
Nir luminescence due to nd3 + ions from the vtes - derived films was observed , with peak shape similar to that of pure complexes . this indicates the ligands indeed effectively shield nd3 + ions from the chemical microenvironment and giving evidence of the lack of strong chemical interactions with the host matrix when the complex was embedded in the vtes - derived matrix 488nm光激发下，观察到薄膜中钕的发光，与纯配合物粉末荧光相比，峰形变化不大，表明配体对钕起着有效的包裹和保护作一浙江大学硕士学位论文用， nd3 +离子的配位环境受基质的影响很小。
As a result , the photocatalytic activities of htawoe / tio2 and htawo6 / cd0 . 8zn0 . 2s were superior to that of pristine samples , and they were greatly increased with co - doping pt particles in the interlayer . the photocatalytic activity of htawo6 / ( tio2 , pt ) was higher than tio2 ( p - 25 ) , which maybe due to that the surface area of htawo6 / ( tio2 , pt ) was 28 times as htawo6 ' s 当该材料受到光激发时，载流子有可能发生客体与客体及客体与基体间的迁移，降低电子和空穴的复合，从而有效提高半导体的光催化活性，且由于该材料易于回收重复利用，因此有望在环保领域得到广泛的应用。
The photocatalytic activities of the xw11 / tio2 ( x = p , si , ge ) composite films were tested via degradation of aqueous azo - dyes , congo red ( cr ) and naphthol blue black ( nbb ) . it was observed that the photocatalytic activities of the three composite films are much higher than that of the pure tio2 film , mainly attributed to the synergetic effect between xw11 and tio2 , i . e . , xw11 - catalyzed electron transfer from the conduction band ( cb ) of photoexicited tio2 to itself 结果表明三种复合膜均具有远高于纯tio _ 2膜的活性，主要归因于复合膜材料中多金属氧酸盐和tio _ 2之间存在的协同效应，即作为强电子受体的多金属氧酸盐接受tio _ 2受光激发形成的导带光生电子，延长了空穴-电子的再复合时间，同时自身仍具有光活性。
