| Abstract: | Addition of the soap ammonyx LO to a solution of 2 × 10-4Mrhodamine 6G in water lengthens the fluorescent lifetime from 3.8 to 5 nsec, and increases the relative quantum yield by ≈ 1.5. Concentrations of soap and solute are those commonly used in cw rhodamine dye lasers. Comparisons are made with rhodamine 6G in ethanol solutions. |
