Abstract

The Hg(6 3P1)-photosensitized luminescence of amine(AM)-alcohol (AL) mixtures and some aminoalcohols has been investigated under conditions of steady illumination at room temperature. For AM-AL mixtures, the intensity of luminescence at 300 nm from an HgAL* complex decreased with increasing amine pressure, while the emission intensity at 360 nm from an HgAM* complex increased upon addition of AL. For aminoalcohols only emission from exciplexes formed between Hg* and an amino group was observed. In order to explain these results, we proposed that a ligand-exchange reaction, HgAL* + AM → HgAM* + AL, effectively occurs in these systems.
