Abstract

The quenching of fluorescence due to the high values of the fluence of the excitation field is studied for three different samples of Rhodamine 6G: ethanol and glycerol solutions and a film of the dye deposited over a silica substrate. High level of quenching is reported for the ethanol solution, while the effect is barely observed for the glycerol solution. The film sample does not exhibit the quenching effect. We also report correlation between the presence of quenching of the fluorescence and the fluence dependence of the fluorescence decay. The results confirm the validity of a model, which suggests this dependence as an explanation of the quenching effect.
