Abstract: Abstract Lifetimes of the luminescences from the self-trapped states of the charge transfer excitons in halogen bridged mixed valence metal complexes have been measured. The lifetimes of [Pt(en)2Br2][Pd(en)2](ClO4)4, [Pt(en)2Cl2][Pd(en)2](ClO4)4 and [Pt(chxn)2Cl2][Pt(chxn)2](ClO4)4 are 300±20 psec, 100±20 psec and 120± 20 psec, respectively. These values are from one to two orders of magnitude shorter than the radiative lifetimes estimated from the oscillator strengths of the free excitons. This indicates that nonradiative decay processes de...
