Rhodamine 6G laser pumped by cathodoluminescence

Soviet Journal of Quantum Electronics, 1984
Cathodoluminescence from a CdS crystal, generated by the action of high-power short-duration electron beam pulses was used to pump a rhodamine 6G (R6G) laser. Measurements were made of the energy spectrum of the electrons in the beam exciting the CdS crystal, of the cathodoluminescence spectrum of CdS, of the absorption and emission spectra of the dye,

Spectroscopic studies of rhodamine 6G dispersed in polymethylcyanoacrylate

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2005
We 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.

Aggregate formation of Rhodamine 6G in anisotropic solvents

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2001
The 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 ...

Adsorption of Rhodamine 6G on saponite. A comparative study with other Rhodamine 6G-Smectite aqueous suspensions

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.

Rhodamine 6G impregnated porous silica: A photoluminescence study

Materials Science and Engineering: C, 2005
Abstract The optical properties of rhodamine 6G dye confined in porous silica are reported. Photoluminescence properties of embedded chromophores in mesoporous hosts can be affected by the surrounding matrices: shifts in emission spectra and variations of photoluminescence quantum yield are found as compared to dye solutions.

Substituent effects on the fluorescent spin-crossover Fe(ii) complexes of rhodamine 6G hydrazones

Inorganic Chemistry Frontiers, 2019
The magnetic properties of Fe(ii) pyridine-2-carbaldehyde rhodamine 6G hydrazone complexes are modulated by the substituents. The desolvated complex displays the correlation between the spin crossover and the fluorescence.

Photocatalytic activity of ZnO composites against rhodamine B and rhodamine 6G

Fibers and Polymers, 2015
The development of nanostructures based on interaction of organic matrix and metal oxide particles (such as polypyrrole/zinc oxide composites) introduces interesting advantages due to synergistic/complementary photocatalytic activity of resulting material.

Molecular-dynamics simulations of pyronine 6G and rhodamine 6G dimers in aqueous solution

Journal of Molecular Modeling, 2006
We 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
