Stimulated resonance Raman scattering of Rhodamine 6G

Optics Letters, 1993
Stimulated resonance Raman scattering (SRRS) of Rhodamine 6G (R6G) has been observed in microdroplets. By increasing the R6G concentration and input-laser intensity, SRRS from R6G can be distinguished from the R6G lasing. SRRS can be further amplified by the lasing gain when the SRRS is near the peak of the lasing gain profile.

On the mechanism of rhodamine 6G fluorescence quenching

Optics Communications, 1972
Abstract The fluorescence of the widely used TPF dye rhodamine 6G is quenched by photons of the ruby as well as the Nd-glass laser. Taking into consideration the polarisation of the ground- and excited-state absorptions of rhodamine 6G a simple model of quenching results.

Efficient photobleaching of rhodamine 6G by a single UV pulse

Applied Optics, 2021
While photobleaching can be detrimental in applications focusing on fluorescence as it lowers the signal strength, it can advantageously provide non-fluorescent tracers in a fluorescent flow and hence be implemented in tracking techniques such as molecular tagging velocimetry (MTV). The photobleaching of rhodamine 6G under a single

Nanostructured Hybrid Systems with Rhodamine 6G

Journal of Dispersion Science and Technology, 2008
We synthesized hybrid materials by sol-gel process, using: methyltriethoxysilane, tetraetylorthosilicate and vinyltriethoxysilane, in the presence of Rhodamine 6G. It was synthesized as well organic-inorganic hybrids with addition of tetraisopropyl orthotitanate and maleic anhydride UV-VIS spectra of dye show two absorption peaks at 499 nm (dimer) and ...

Quantum control of Rhodamine 6G in solution

Frontiers in Optics, 2006
We present coherent control of dye photoluminescence in solution obtained with a novel, compact, and high-resolution phase modulator in reflective mode. Analysis of the populations used in the optimization process is also presented.

Rhodamine 6G Encapsuled Mesoporous Silica Channels

Advances in Science and Technology, 2008
We report the effect of solvent on the rhodamine 6G encapsuled into channels of mesoporous silica, synthesized by two-step process that gives intermediary stable hybrid micelles. Mesoporous materials have been obtained by the method that involves surfactant micelles (mainly cationic) and inorganic precursor of the structure to be obtained.

Adsorption of rhodamine 6G at the water‐air interface

physica status solidi c, 2008
AbstractWe wanted to detect and quantify adsorption of Rhodamine 6G (R6G) at the air/water interface to supplement previous work using second harmonic generation [1–4]. We found that at incidence angles close to the Brewster angle this can be achieved, even at very low bulk concentration.

Photostability of porous silica – rhodamine 6G hybrid samples

Materials Science and Engineering: C, 2006
Abstract In the last decades solid-state tunable lasers were prepared by embedding dye molecules into sol–gel matrix. The main advantage with respect to the liquid dye solution is the decrease of health and environmental hazards. However the desired dye photostability, which is mainly related to the photochemical degradation of organic molecules in ...

Photochemical stability of rhodamine 6G in solution

Optics Communications, 1978
Abstract 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.
