Time-resolved studies of the magnetic field effect on pyrene-dimethylanilie exciplex luminescence in non-alcoholic solvent mixtures (dielectric constant of 16) have been performed with the help of a time-correlated single-photon counting technique. The shape of the time-variation curve is interprete

The effect of a magnetic field on the pyrene-N,N-dimethyIaniIine esciples luminescence in methanol has been studied using an improved phase-sensitive detection technique. The wavelength dependence of B,,z, the effect of isotopic substitution of the solvent, and the consequences of using mixed donors
It is observed that the lanthanide acetylacetonates (Ln( acac) ,) quench the magnetic field effect of pyrene-dimethylaniline exciplex luminescence. The quenching rate constants (Q) for the different Ln 3+ ions follow the same trend as was previously observed in the photolysis of quinones and ketones
