Specifically, it is of interest how the emission behaviour is changed by the coupling of two antenna arms via a small gap. Experimental techniques applied include dark-field spectroscopy and two-photon luminescence UR - https://www.ksp.kit.edu/9783866447653 UR - https://directory.doabooks.org/handle/20.500.12854/55295 ER -
