The UV–VIS absorptive and emissive properties of three laser dyes, viz. Rhodamine 6G, Rhodamine B and Rhodamine 101, have been studied in ethanolic and methanolic solutions. Time-resolved methods were used to study the decay of the first excited singlet state of each dye.

The photophysics of rhodamine B
Journal of Photochemistry, 1982Abstract The effects of solvent viscosity and dielectric constant on the photophysics of rhodamine B in its protonated and zwitterion forms were studied. The internal conversion rate is dependent on the S 1 -S 0 energy separation and increases when this gap is lowered through rotation of the diethylamino groups. Comparison is made with rhodamine 640

A new application of Rhodamine 200 B (Sulfo Rhodamine B)
Dyes and Pigments, 1995Abstract The laser dye Rhodamine 200 B (Sulfo Rhodamine B) (CI Acid Red 52) can be used as a fluorescent counterion for the transfer of various cationic species (e.g. cationic surfactants and crown-complexes of metal ions) into a chloroform phase. The extraction of ionic associates is found to be independent of the acidity of the aqueous phase within

Labeling Mitochondria with Rhodamine 123
Cold Spring Harbor Protocols, 2011INTRODUCTIONRhodamine 123 is a cationic fluorescent dye that is used to specifically label respiring mitochondria. The dye distributes according to the negative membrane potential across the mitochondrial inner membrane. Loss of potential will result in loss of the dye and, therefore, the fluorescence intensity.

Optical properties of Rhodamine B and Rhodamine 6G on silver surfaces
Pramana, 1988The transmission spectra of Rhodamine B and Rhodamine 6G dyes coated on silver island films for various thickness were recorded. A strong coupling between the silver particle plasma resonance and the dye molecules is observed. The absorption of dye molecules increases when the absorption band of individual dyes and silver particles overlaps.

Conjugation of Antibodies to Fluorescein or Rhodamine
2005The isothiocyanate derivative of the fluorophore, fluorescein or rhodamine, is coupled to the amino groups of IgG antibody in a one-step procedure and excess label is removed by gel filtration.

A range of basic dyes and an acidic dye have been dyed onto wool at room temperature using dimethyl sulfoxide as the solvent. When fluorescent Rhodamine dyes are dyed to low depths of shade by this method, the lightfastness of the dyeings is enhanced compared with wool dyed conventionally.
