| 摘 要： | 报道了有机无机异质节中稀土配合物的电致发光,器件结构为:ITO/PVK:Rare Earth Complex/无机材料/Al,其中无机材料可以选用ZnS,ZnSe,ZnO等.在这种结构的器件中,均获得了比较好的稀土离子的特征发射.以无机材料ZnS为例,讨论了异质节中稀土配合物的电致发光及优势.ZnS的电介质系数比PVK的电介质系数大3倍多,将有更大部分的电压降落在PVK层上,使PVK层内的电场强度增大,从而可以提高空穴在PVK层内的迁移速度,提高了空穴注入数目,有利于载流子的平衡.

| Abstract: | Luminescence of rare earth complex based on organic-inorganic heterostructure is reported.The structure of the device is ITO/PVK:Tb/inorganic material/Al,where inorganic material includes ZnS,ZnO or ZnSe.For this structure,the authors obtained the characteristic emission of Tb ion.A large part of driving voltage was dropped on the PVK layer because the dielectric constant of ZnS is 3 times bigger than that of PVK.The electric field strength in PVK layer was improved,so the velocity of hole in PVK was increased.The balance of injected charge was enhanced. |
