Interatomic Coulombic Decay (ICD) has recently been subject of many experiments. It is a new decay path for excited atoms in weakly bound systems. Here we introduce fluorescence as an as yet not considered tool to investigate ICD. In noble gas clusters fluorescence decay paths should be observable due to ICD, that are not possible in the atomic case. A more elegant possibility offer mixed clusters. After excitation of one kind of atom fluorescence of the cluster partner can be measured. We introduce the planned spectroscopy experiments to proof and investigate the ICD-process and we present results of preliminary experiments on fluorescence spectroscopy of noble gas atoms and clusters.
