Quenching and Energy Transfer by the Same Substance

· Journal of Chemical Physics
The quenching by o-terphenyl of the gamma-ray induced fluorescence of o- xylene/9,10-diphenylanthracene solutions does not give the usual linear dependence of I0/I on quencher concentration. The effect is ascribed to a quencher concentration-dependent energy transfer from the solvent to o-terphenyl which has a finite transfer probabllity to the fluorescent solute. The interpretation was confirmed by the enhancement of energy transfer caused by the addition of o-terphenyl to a solution of a fluorescent solute in tri-n- butylphosphate, a solvent having a very low transfer efficiency.
