WebFigure 5 shows the dynamics of R6G and PC fluorescence dyes for switched on and off microwave radiation with different capacities. The absorption of microwaves leads to fluorescence increasing for R6G solution and fluorescence quenching for RC. The gradual decrease in fluorescence intensity is caused by photodestruction of organic dye molecules.
