为了研究等离子体激元环境对磁偶极子和电偶极子自发辐射的影响，我们研究了Eu 3+离子在金纳米带阵列附近的发光。发射动力学，发射偏振，和辐射模式的显着变化已被观察到在对应于等离子体共振的波长范围内。发现等离子体共振对磁偶极跃迁D-5（0）-> F-7（1）的影响与其对电偶极跃迁的影响有很大不同。这使得含Eu 3+的配合物有希望在超材料和等离子体系统中绘制局部磁场和电场分布。(C)2013年美国光学学会
In order to investigate the effects of plasmonic environments on spontaneous emission of magnetic and electric dipoles, we have studied luminescence of Eu3+ ions in close vicinity to gold nanostrip arrays. Significant changes in the emission kinetics, emission polarization, and radiation patterns have been observed in the wavelength range corresponding to the plasmonic resonance. The effect of the plasmonic resonance on the magnetic dipole transition D-5(0)-> F-7(1) is found to be very different from its effect on the electric dipole transitions. This makes Eu3+-containing complexes promising for mapping local distributions of magnetic and electric fields in metamaterials and plasmonic systems. (C) 2013 Optical Society of America
