Luminescence in Applied Magnetic Fields

Abstract

Metal complexes and solids were synthesized and subjected to photoexcitation measurements under the influence of externally applied magnetic fields. The photoluminescence of complexes of rhodium (I) and iridium (I) displayed both field-induced emission bands and a many-fold shortening of the excited state lifetime. Both the decay rates and the induced emission band intensities showed a quadratic dependence on the applied field. A several fold shortening of the phosphorescence from the octaphosphitoplatinum (II) anion under an applied field (50 T) was also observed. Spectroscopic studies of several bis (N-heterocyclic) complexes of copper (I) were also concluded and complete group-theoretic assignments of the charge-transfer excited states were made. The technique of Thermal Modulation was perfected and applied to the study of the exited states of transition-metal complexes with near-degenerate emitting states.
