| 稀土配合物的結構由中心離子和配體兩部分組成，其中具有較強配位能力和合適三線態(tài)能級的中性配體在和稀土離子配位的同時，不僅有助于提高光致和電致發(fā)光性能，還可以提高稀土配合物的熒光發(fā)射強度、揮發(fā)性和穩(wěn)定性等。據(jù)報道，當前稀土銪配合物作為電致發(fā)射材料的最大問題之一是因為其載流子在遷移率（尤其是電子遷移率）比較低，僅是傳統(tǒng)LED無機材料的0.01-0.1%,解決這一問題的有效途徑就是在配合物中引入合適的中性配體. 在中性配體方面，亦可以通過增加分子的剛性來降低能量的散耗進而提高配合物的熒光效率(photoluminescence quantum yields, PLQY)。另外，含有剛性配體的OLED稀土發(fā)光材料還可以降低分子之間的堆積和相互作用進而能減少濃度淬滅及“T-T”熄滅和提高器件的外量子效率。 |

Rare earth complexes, whose structure is composed by center cations and ligand, have strong coordination ability and appropriate neutral ligand with triplet state level . It not only may be helpful to improve the properties of photics and electroluminescence, but improve the fluorescent emission intensity, volatility and stability when the neutral ligand was coordinated with rare earth ions. According to the reports, the greatest current problem of rare earth europium complex used as electric emission materials was that the mobility(especially the electronic mobility) of europium complex carriers were relatively low, only 0.01-0.1% of traditional LED inorganic materials. Introducing the neutral ligand into complexes was an effective solution to the problem. The photoluminescence quantum yields(PLQY) could be improved by increasing molecular rigidity to reduce energy dissipation in neutral ligand field.Furthermore, OLED rare earth luminescent material with rigid ligand could decrease the accumulation and interaction between molecule to reduce concentration quenching, “T-T”extinguish and to improve the external quantum efficiency of devices. |

這是自己翻譯的，請大神修改下 The structure of rare earth complexes is composed of the central ions and ligands, which has strong coordination ability and appropriate triplet energy neutral ligands with rare earth ions coordination at the same time, will not only help improve the light and electroluminescent performance, also can improve the fluorescence emission intensity of rare earth complexes, volatile and stability, etc.According to the report, the rare earth europium complexes as one of the biggest problems of electric emission materials because of its carrier in mobility, especially electron mobility, low , is only part of the traditional LED inorganic material 0.01 0.1% , the effective ways to solve this problem is the introduction of appropriate neutral ligands in the complexes. In terms of neutral ligands, also can increase the rigid molecules come loose to reduce energy consumption and improve complexes fluorescent efficiency (photoluminescence quantum yields, PLQY).In addition, rigid ligand containing rare-earth luminescence materials of OLED can also reduce the accumulation and interactions between molecules, in turn, can reduce the concentration quenching and "T - T" go out and improve the external quantum efficiency of the device |

| The rare earth complexes is made up of the central ions and ligands. while the rare earth ions mates the neutral ligand with strong coordination ability and suitable level of triplet ,It not only contributes to improving the photoluminescence and electroluminescence performance， but also the fluorescence emission intensity, volatility and stability of the lanthanide complexes. According to reports,at currently,one of the biggest barriers of Europium complexes' application to electroluminescent emission materials is cused by Relatively low carrier mobility( especially the electron mobility).Just equal to 0.01-0.1% of the traditional LED inorganic material. an effective way to solve this problem is to introduce a suitable neutral ligand to the complexes. as to neutral ligand,we can increase the rigidity of the molecule to reduce energy dissipation and to improve the photoluminescence quantum yields of ligand complexes. In addtion, OLED rare earth luminescent materials containing rigid ligands can also reduce the accumulation and interaction of molecules and thus can reduce the concentration quenching and "TT" extinguishment then improve the external quantum efficiency of the device. |
