Abstract

The Hg(63P1)-photosensitized luminescence of amine (AM)-alcohol (AL) mixtures was investigated under conditions of steady illumination at room temperature. The quantum efficiencies of the luminescence from the HgAM* complex for AM-AL mixtures were found to be much larger than those for pure amines. This finding was explained by the efficient formation of HgAM* complexes through the ligand-exchange reaction, HgAL* + AM → HgAM* + AL, in a previous paper. From the quantum efficiencies of luminescence for amines, alcohols and AM-AL mixtures, the efficiencies of complex-formation and light-emitting steps could be determined separately. The rate constants for radiative and non-radiative processes from the exciplexes were determined for the first time.
