C60+ Near-IR Emissions: Astronomical Relevance. — •Dmitry Strelnikov1, Bastian Kern2, and Manfred Kappes1 — 1Physikalische Chemie, KIT, Karlsruhe, Germany — 2MPI for Solid State Research, Stuttgart, Germany
Recently, five Diffuse Interstellar Bands (DIBs) were assigned to C60+ [1,2]. While investigating C60+ in various cryogenic matrixes, we have observed LIF in the near-IR, when exciting the near-IR vibronic bands of C60+. Power dependence measurements revealed a one-photon LIF process. In contrast, excitation in the UV does not lead to the emission of C60+ in the vicinity of its NIR absorptions. We propose to search for C60+ near-IR emissions in the fullerene containing reflection nebulae.
