Nanostructured Metal Aggregate-Assisted Lasing in Rhodamine 6G Solutions
We report on the experimental demonstration of considerable lowering of stimulated luminescence (lasing) threshold in R6G laser dye solution doped with metal agglomerates (Ag, Al, Ni) upon second harmonic of Nd:YAG-laser illumination. Due to strong structural coupling between individual nanoparticles, they may form fractal agglomerates providing an extreme optical pump-field enhancement near th...
متن کاملLuminiscent dye Rhodamine 6G doped monolithic and transparent TEOS silica xerogels and spectral properties
Sol–gel process was used for the preparation of Rhodamine 6G (R6G) doped silica xerogels, using tetraethylorthosilicate [TEOS, Si(OC2H5)4] as the precursor for the silica network. Silica alcosol was prepared by hydrolysis and polycondensation of ethanol (EtOH) diluted TEOS in the presence of citric acid (CTA) catalyst. The ethanolic R6G was added to the alcosol to trap R6G molecules inside the ...
متن کاملDynamics of molecular diffusion of rhodamine 6G in silica nanochannels.
We describe a method to study diffusion of rhodamine 6G dye in single silica nanochannels using arrays of silica nanochannels. Dynamics of the molecules inside single nanochannel is found from the change of the dye concentration in solution with time. A 10(8) decrease in the dye diffusion coefficient relative to water was observed. In comparison to single fluorescent molecule studies, the prese...
متن کاملPreparation and Spectroscopic Studies of Rhodamine 6G Doped Polystyrene
In the present work, polys tyrene (Ps) doped with Rhodamine 6G was prepared. The infrared absorption spectra were obtained and dis c u s s e d in the range (400-4000 cm ). A new band appeared -1 2 at 3300 cm due to NH in the spectra of PSRhodamine 6G. In the spectra of Ps – Rhodamine 6 -1 G this band appeared at 1599 ass igned to C = O s tretching vibration. This is due to interaction between t...
متن کاملRhodamine 6G hexachloridostannate(IV) acetonitrile disolvate
In the title compound, bis({6-ethylamino-10-[2-(methoxycarbonyl)phenyl]-2,7-dimethylxanthen-3-ylidene}ethanaminium) hexachloridotin(IV) acetonitrile disolvate, (C(27)H(29)N(2)O(3))(2)[SnCl(6)]·2C(2)H(3)N, the octa-hedral SnCl(6) (2-) anion lies on an inversion center. The xanthene ring system is essentially planar, with an average deviation of 0.020 Å, and the substituent benzene ring forms a d...
