发射光谱

Like the visible spectrum, an atomic emission spectrum is a continuous range of colors.

像可见光谱，原子发射光谱是一个持续不断各种颜色。

The excited and emission spectra of anthrone derivative, lactoflavin and chlorophyll a in different solvents are taken and the fluorescence yields has been estimated. The results show that the emission spectrum depends on the structure of molecule, and shifts to red with increasing of number of π electrons in the molecule.It is...

本文通过考察三种具有不同π电子数的有机共轭分子在不同溶液中的光谱特性，观察其激发光谱和发射光谱的变化情况，比较同一分子在不同溶液中的荧光量子产率，并通过对各类有机共轭分子溶液的光谱分析比较，以获得有机共轭分子的发光受溶剂影响以及同一溶液中不同有机共轭分子间发生非辐射共振能量转移的信息。

The emission of N_2 in discharge gap is detected using optical emission spectrophy. The discharge reactor was put in lightproof box to avoid the disturbance from outside lights. A small hole was drilled in one sidewall of the box, and the fibre was mounted coupling to the inlet (1mm) into the hole. A tube with the inner diameter of 1.1mm was set in the front of the hole. In this way, only the light from a certain direction emitted from the discharge reactor could transfer into the inlet through the tube. The reactor could be moved in the vertical direction of the fibre, and the spectrometry can collect the total emission along the fibre inlet in single-shot measurement.

利用光学发射光谱仪对多针对板电晕放电中放电间隙内的N_2发射光谱进行测量，放电反应器置于暗箱中以避免外界对光谱测量的影响，将光谱仪的光纤耦合入口固定在暗箱侧壁的小孔内，小孔孔径为光纤耦合入口直径，在小孔前方安装孔径为1.1mm的细直管，只采集与光纤耦合入口在同一直线上的发光，避免放电区其它区域的发光被同时接收。

Here we introduced oxadiazole moiety to theside-chain of Ph-PPV to enhance the electron transport properties. The luminescenceefficiency and luminescence brightness (1.33cd/A, 9400 cd/m~2) of the Ph-PPV withside oxadiazole moiety are much higher than non-oxadiazole Ph-PPV (0.70 cd/A,2300 cd/m~2), and these polymers emitted green light which unaffected by theintroduction of oxadiazole moiety. Anthracene has a rigidity and planar structure which shows high photoluminescenceand thermo-stability.

A novel bis (o-aminobenzophenone) s monomer is synthesized, and is used to get three different polyquinolines containing phenylamine moiety through Frieldlander reaction.

In quantitative measurement of skin color,tristimulus values were obtained based on reflectance spectrum .

在皮肤颜色的定量测量中，颜色三刺激值是基于反射光谱获得的，而与反射光谱相比，荧光发射光谱可以反映皮肤组织更深层结构的信息。

Meanwhile,the peaks of excitation spectra and fluorescence emission spectra are decided by examining the three-dimensional and two-dimensional fluorescence spectroscopy using ventricles and atriums with dye.

Fluorescence emission spectra and UV absorb spectra analysis have been undertaken to test the influence of solvent polarity on the lowest excited singlet state of the tertiary amines. The absorption maxima were red-shafted slightly, and the emission maxima were red-shafted strongly, which showed all of the three compounds were found to be essentiallyππ* in character, which makes for the formation of triplet-exciplex state and the subsequent reactions,?known as photo-reduction and hydrogen-abstraction.
