Rhodamine 6G–SiO2 hybrids: A photoluminescence study
Journal of Non-Crystalline Solids, 2005Abstract Photoluminescence properties of Rhodamine 6G dye confined in porous silica are reported. Different types of organic–inorganic hybrids have been prepared and characterized: class I and II systems have been investigated as a function of rhodamine 6G concentration.

Studies on optical phase conjugation by degenerate four-wave mixing in aqueous rhodamine 6G solutions and in rhodamine 6G embedded in polyvinyl alcohol thin films are presented. The experiments were performed at 532 nm using picosecond pulses. Strong nonlinearities were observed in both media for three different polarization configurations of the ...

Thermostimulated Conductivity in Organic Dyes (Rhodamine 6G)
Physica Status Solidi (a), 1972Parameters of charge carrier traps in films of the organic semiconductor rhodamine 6G were determined as a result of investigations on thermostimulated conductivity, isothermal decay of TSC, and distant stages of photocurrent relaxation. The traps are located in the forbidden band at a depth of 0.32 eV and are practically discrete.

Langmuir, 1995
Absorption and fluorescence spectroscopies are applied to study the adsorption of rhodamine 6G on saponite in aqueous suspensions. The interpretation of the experimental results suggests that the dye can be adsorbed as the monomeric and the dimeric forms on both the external and the interlamellar surfaces of the clay.

Solvent effects on the gain of rhodamine 6G
Applied Physics, 1980The effect of solvents on the gain and the peaks of gain spectra is investigated for rhodamine 6G (R6G) under nitrogen laser pumping. The non-specific solute-solvent interaction for R6G is found to be mainly dispersive. Additional shifts produced for R6G in certain solvents are explained as due to hydrogen bonding.

Aggregate formation of Rhodamine 6G in anisotropic solvents
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2001The aggregation of Rhodamine 6G in liquid crystalline solutions was studied using polarised spectroscopy and in a guest-host system based on homogeneous-homeotropic alignment. The orientation of the dye molecules (guest) was controlled using an electric field, and this enabled the contrast ratio R of the dye to be obtained by electrically switching ...

Spectroscopic studies of rhodamine 6G dispersed in polymethylcyanoacrylate
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2005We report here electronic absorption, fluorescence and resonance Raman studies of rhodamine 6G laser dye dispersed in the polymethylcyanoacrylate matrix. In the electronic absorption and fluorescence spectra of dispersed rhodamine 6G, band maxima are red shifted compared to solution. Raman spectra show some new bands.

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.

Human cell variants resistant to rhodamine 6G
Somatic Cell and Molecular Genetics, 1985Two variants have been isolated from the cultured human cell line VA2-B which are resistant in vivo to the mitochondrial-specific fluorescent dyes rhodamine 6G and rhodamine 123. Both mutants are cross-resistant to ethidium bromide but are sensitive to both colchicine and chloramphenicol.
