Abstract：The fluorescence property of DCM in water solution with added different concentration of SDS is reported. With increasing the concentration of SDS in water, the solubility of DCM and the fluorescence intensity increase. When the concentration of SDS increases from 0.025 to 0.5 mol·L-1,the maximum fluorescence relative intensity is enhanced by a factor of 95. A powerful dye laser at wavelength of 648 nm was generated in the solution of DCM in water with SDS exited by a 532 nm laser. It shifts 13 nm compared with the dye laser wavelength of the solution of DCM in ethanol. And enhancement of SRS of C6H6 was achieved both in the solution of DCM in water with SDS and in the solution of DCM in ethanol. The result is that the second, the third and the forth order Stokes of C6H6 are all enhanced. But the former mainly enhances the forth order Stokes(632 nm) and the enhancement gain coefficient is 8.5, while the latter mainly enhances the third order Stokes(595 nm) and the enhancement gain coefficient is 2.5. The mechanism of solubility, fluorescence enhancement and its possible application are discussed.
