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+). According to the experimental result, we develop the novel sensor for Cu~(2+).

研究结果，吡啰红与CdS之间作用形式是染料聚集在CdS的表面使得CdS不易聚集，但同时也降低了CdS的发光的量子效率；罗丹明B、罗丹明6G、丁基罗丹明B均与CdS之间存在能量转移，位阻效应使得能量转移效率最高的BRhB的相对荧光强度增大最小；中性红与CdS的能量转移效率更高，同时推测可能使CdS-TGA上的-COOH与部分NR的-NH_2发生偶联导致粒子变大而发生荧光光谱的红移；番红花红与CdS是相互荧光猝灭，可能是ST的-NH_2与CdS-TGA上的-COOH发生偶联使得纳米粒子变大以及二者形成基态复合物的共同作用的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
