Excited state properties of Tl2B12H12. Metal-centered photoluminescence
Authors:Horst Kunkely
Institution:Institut für Anorganische Chemie, Universität Regensburg, D-93040 Regensburg, Germany
Abstract:The compound Tl2B12H12 which consists of icosahedral View the MathML source anions and Tl+ cations shows a metal-centered r.t. luminescence at λmax = 530 nm which originates from the lowest-energy sp triplet of Tl+. This emission indicates a considerable covalent interaction between Tl+ and View the MathML source which is based on the hydridic nature of the boron cluster.
Keywords:Electronic spectra  Metal-centered excited states  Photoluminescence  Phosphorescence  Thallium  Borane
