Pyronine B adheres to on the surface of CdS and prevents CdS aggregating, which leads to the decrease of fluorescence quantum yield of CdS. Fluorescence resonance energy transfer happens from CdS to Rhodamine B, Butyl rhodamine B and Rhodamine 6G, respectively. There is a higher FRET efficiency between CdS and Neutral red with the value being 0.282. Moreover, coupling reaction between -NH_2 of Neutral red and -COOH of CdS -TGA leads to red shift of CdS fluorescence spectrum. The reaction also occurs between Safranine T and CdS. At the same time, the Fluorescence of ST is quenched by forming ST -CdS ground state complex. Chapter 6, CdS QDs modified by chitosan and polyethyleneimine can be quenched by Cu~(2+).

We note from the further studies that in the crystals, which sharing the similar crystal structures and coordinational environments, the magnitude of the Stokes shift of the luminescence of the dopant ion is in line with the average covalency of the replaced lattice site. This is because that the nature of Stokes shift is the energy transfer from the luminescent ion to the host lattice. The value of this energy is determined by the frequency of the host lattice in which the frequency is controlled by the chemical bond characters.

更深入的研究发现，在晶体结构和中心离子配位环境非常相似的系列晶体中，掺杂离子发射光的Stokes位移值与其所取代格位的平均共价性成正比的关系，这是由于Stokes位移的本质是发光离子在发光过程中向基质以光波辐射的形式传递能量，这一能量的大小是由基质的振动频率决定的，而基质的化学键性质恰恰决定着基质的振动频率。

Further picosecond PL studies on dendronized PFs show that the fluorene-based emission in dilute solution follows a single exponential decay, whereas those in thin film decayed in a multi-phase manner and the lifetime prolongs with the generation of dendronization. These observations are discussed in terms of dispersive transport happening between adjacent chains in film. The dispersive relaxation can be controlled by site isolation of bulky dendrons. Our results prove that dendronization is highly effective in controlling the inter-chain interactions of fluorene-based polymers.

bioluminescence：生物发光

2.生物发光(bioluminescence)典型例子为萤火虫发光. 反应底物为萤火虫光素(fireflyluciferin),在荧光素酶(luciferase)的催化下利用ATP产能,生成激发态的氧化荧光素(oxyluciferin),后者在回复到基态时多余的能量以光子形式放出. 反应式如下:

black body radiation：黑体幅射

依据黑体幅射(black body radiation)的研究,任何温度的物体热辐射产生的光(称为电磁波),其能量与辐射出的波长成反比. 所以物体温度越高,它辐射出的电磁波能量越高,而发光的波长越短,亦即偏向蓝光;反之辐射出的电磁波能量越低,而发光的波长越长,

chemiluminescence：化学发光

化学发光(Chemiluminescence)指的是能量由化学反应所提供的,也就是说在一个化学反应中释放出光子信号. 能够产生化学发光现象的化学反应是非常少的. 化学发光最好的例子如下:

luciferin：萤光素

原来在这些萤火虫的发光器里头含有一种叫做萤光素 (luciferin) 的含磷化学物质. 这种萤光素在发光酵素的催化下会进行一连串的生化反应,而光是这些复杂生化反应下的产物. 由於在反应过程中大部份的能量都用来发光,只有2-10%的能量转化为热能,

luminescence：发光

"发光"(Luminescence)就是发射不具热量的光线. "萤光"(Fluorescence)是当某些物质受到紫外线能量的激励时所发射的光. 当这种激励移去时,就停止发光. "磷光"(Phosphorescence)是在激励根源移去以后仍然继续发射光线.

photoluminescence：光致发光

光致发光包括光吸收、能量传递、光发射等过程,这些过程与材料结构、成分及环境原子排列有关,光致发光技术[简介]光致发光(photoluminescence) 光致发光(photoluminescence) 材料通过吸收光子产生激发态的辐射跃迁.

thermoluminescence：热释光

热释光(thermoluminescence)是指固体在受辐射作用后积蓄的能量在加热过程中以光的形式释放出来的现象,又称热释发光或加热发光,其发光强度与温度的关系叫热释发光曲线.

dopant：杂物

而在阳极的选择上,则必需是一个高功函数又可透光的材质,这样的选择并不多,所以ITO(indium在后续的研究当中发现,OLED可藉由在发光层中掺杂一不等浓度的掺杂物(dopant),使得主发光体(host)的能量得以转移至掺杂物上而改变原本主发光体的光色以及发光的效率,
