Answer
Rhodamine B is a bright red fluorescent xanthene dye. Its chemical formula is C28H31ClN2O3. It is soluble in water and methanol, and has an excitation/ emission maxima of 568/583 nm. Rhodamine functions as a water tracer fluorescent and is used extensively as a staining fluorescent dye.
Rhodamine 6G is a dark reddish purple organic laser dye. Its chemical formula is C28H31N2O3Cl. It is soluble in water and methanol and has an excitation/emission maxima of 525/548 nm. Rhodamine 6G has a high quantum yield for fluorescence to study probes and can be used as a fluorescence tracker.
