Specific Effect of Microwaves on the Aqueous Solution of Rhodamine 6G According to Fluorescence Analysis
Keywords:microwave heating, fluorescence, organic dye, percolation model
The effect of microwaves with a frequency of 2.45 GHz on the fluorescence of the aqueous solution of the organic dye rhodamine 6G has been studied. Deviations in the dynamics of the relative intensity and peak wavelength changes in the cases of microwave absorption and subsequent cooling of the solution, on the other hand, and contact heating and subsequent cooling, on the other hand, were registered. The obtained results are interpreted with the help of the percolation model. It is assumed that the electric component of the electromagnetic wave can directly affect the structure of the percolation cluster formed by the network of hydrogen bonds.
