Abstract：It is reported that the Rhodamine 6G fluorescence in water solution changes with different concentration SDS excited by a 532 nm laser. A small amount of SDS in Rhodamine 6G water solution will reduce the intensity of fluorescence. More SDS enhances R6G fluorescence. The enhancement ratio can reach up to 3.1 when SDS concentration is 6×10-2 mol·L-1 in 5×10-5 mol·L-1 R6G water solution. Dye laser threshold decreases when SDS concentration is 2×10-2 mol·L-1 in 1×10-4 mol·L-1 R6G water solution. The physical mechanism of the phenomena is analyzed by the absorption spectra of different concentration R6G water solutions and the fluorescence spectra of R6G water solutions adulterated with different concentration SDS.
