Fluorescence spectroscopy of Rhodamine 6G: Concentration and solvent effects
Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2014Rhodamine 6G (R6G), also known as Rhodamine 590, is one of the most frequently used dyes for application in dye lasers and as a fluorescence tracer, e.g., in the area of environmental hydraulics. Knowing the spectroscopic characteristics of the optical emission is key to obtaining high conversion efficiency and measurement accuracy, respectively.

Photobleaching of Rhodamine 6G in polyacrylonitrile matrix
Applied Physics Letters, 1974The photobleaching of Rhodamine 6G (Rh:6G) in the polyacrylonitrile (PAN) matrix was studied at 5145 Å as a function of temperature. Photobleaching yield numbers were measured at room temperature and 106 °K. The quantum efficiency for fluorescence and the absorbtion cross sections were measured both for the solid polymer dye system and the liquid ...

Properties of Rhodamine 6G in vapor phase
Journal of Applied Physics, 1975Basic parameters of optical interaction in Rhodamine 6G in vapor phase are measured from the experimental result that the intensity of emission saturates with increasing intensity of pumping argon laser light. The quantum yield of fluorescence obtained in 0.13 and the cross section of absorption is 2.1×10−16 cm2 at a wavelength of 488 nm.

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.

Molecular-dynamics simulations of pyronine 6G and rhodamine 6G dimers in aqueous solution
Journal of Molecular Modeling, 2006We have carried out molecular-dynamics (MD) simulations on dimers of the positively charged laser dyes pyronine 6G (P6G) and rhodamine 6G (R6G) in aqueous solution, generating trajectories of 2.5 ns for various computational protocols. We discuss how the choice of atomic partial charges and the length of the trajectories affect the predicted structures

Efficient lasing action of rhodamine 6G in Nafion membranes
Chemical Physics Letters, 1996Efficient lasing action is observed in Rh 6G/Nafion Na+ and Rh 6G/Nafion H+ membranes. The dye-embedded Nafion Na+ membranes are found to have excellent photostability and lasing properties as those of sol-gel materials.

Spectrophotometric determination of uranium with anthranilic acid and rhodamine 6G
Talanta, 1980The reaction of the uranium-anthranilic acid complex to form an ion-association complex with Rhodamine 6G provides a means for its estimation. The anionic primary complex is suggested to be a mixed-ligand complex of uranium with anthranilic acid and its oxidation products. The method is sensitive ( = 6.25 x 10(4) 1.mole(-1).cm(-1) at 575 nm) and fairly

Removal of rhodamine 6G with different types of clay minerals
Chemosphere, 2018With an increased use of color dye in textile industries and elevated fabrics output, more scientific studies and technology developments are needed to effectively treat wastewater containing dyes. However, better understanding of the interactions between dyes and suspended solids is a necessity to advance such developments.

Photochemical stability of rhodamine 6G in solution
Optics Communications, 1978Abstract The photochemical stability of Rhodamine 6G under ultraviolet and copper-vapour laser irradiation has been determined. A strong dependence of this reaction on the solvent has been found. The results indicate a free-radical mechanism as a possible reaction pathway for photobleaching.

Fluorescence quenching of rhodamine 6G in methanol at high concentration
Chemical Physics, 1986Abstract The fluorescence lifetime of rhodamine 6G dissolved in methanol is measured over a wide concentration region from 10 −5 to 0.6 mol/l. The rapid reduction of fluorescence lifetime above 10 −2 mol/l is found to be mainly due to energy transfer to quenching centers.
