【摘要】 稀土离子(LnⅢ)丰富的4f电子跃迁能级,使稀土发光材料获得重要而广泛的应用.稀土配合物中天线基团的引入,弥补了稀土离子f-f跃迁禁阻而导致吸收较低的不足.而具有三重态吸收的过渡金属配合物作为天线基团,更使稀土离子的激发窗口红移.相关研究具有重要的理论意义和实际应用价值.本文主要综述近年来有关铱(IrⅢ)-稀土(LnⅢ)异核发光配合物方面的研究进展.更多还原

【Abstract】 Lanthanide luminescent complexes have attracted considerable interests in broad fields due to the rich photophysical properties of 4f electron transition levels.Introduction of antenna groups for the lanthanide complexes can cover the shortage of low absorption coefficient due to inhibition of f-f transition.Among which,d-block triplet complexes have been proved to be good antennas as they also improve emission efficiency and extend excitation windows of lanthanide complexes.In this paper,we mainly focused on the research progress of IrIII-LnIIIheteronuclear complexes,based on their important theoretical significance and great application value.更多还原
