| 稀土配合物的结构由中心离子和配体两部分组成，其中具有较强配位能力和合适三线态能级的中性配体在和稀土离子配位的同时，不仅有助于提高光致和电致发光性能，还可以提高稀土配合物的荧光发射强度、挥发性和稳定性等。据报道，当前稀土铕配合物作为电致发射材料的最大问题之一是因为其载流子在迁移率（尤其是电子迁移率）比较低，仅是传统LED无机材料的0.01-0.1%,解决这一问题的有效途径就是在配合物中引入合适的中性配体. 在中性配体方面，亦可以通过增加分子的刚性来降低能量的散耗进而提高配合物的荧光效率(photoluminescence quantum yields, PLQY)。另外，含有刚性配体的OLED稀土发光材料还可以降低分子之间的堆积和相互作用进而能减少浓度淬灭及“T-T”熄灭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. |

这是自己翻译的，请大神修改下 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. |
