稀土配合物Tb(p-MBA)3phen的有机电致发光 总被引:2,自引:0,他引:2
合成了一种新型的稀土铽配合物材料Tb(p-MBA)3phen,把它作为发光材料应用于有机电致发光中.把铽配合物掺杂在导电聚合物PVK中采用旋涂法制得发光层,并利用AlQ作为电子传输层制作了单层、双层有机电致发光器件:器件1(ITO/PVK):Tb(p-MBA)3phen/Al;器件2(ITO/PVK):Tb(p-MBA)3phen/AlQ/LiF/Al,得到了纯正的、明亮的Tb3 离子的绿光发射,4个特征峰分别对应着能级5D4到7Fj(j=6,5,4,3)的跃迁,而PVK的发光完全被抑制.研究了两种器件的电致发光性能,并通过选择AlQ的厚度得到了发光性能较好的器件,其最大亮度在20 V时达到152 cd·m-2. 相似文献

The vector correlations between products and reagents for the reactions Ne+H + 2 , Ne+D + 2 , and Ne+T + 2 are calculated by means of the quasi-classical trajectory method on a new potential energy surface constructed by Lü et al. [J. Chem. Phys. 2010 132, 014303]. The polarization-dependent differential cross-sections (2π/σ)(dσ 00 /dω t ), (2π/σ)(dσ 20 /dω t ), (2π/σ)(dσ 22+ /dω t ), and (2π/σ)(dσ 21 /dω t ), and the distributions of P (θ r ), P (φ r ), and P (θ r ,φ r ) are calculated. The isotopic effect, which is associated with the difference in mass factor among the three reactions, is revealed. 相似文献
