Photocatalytic activity of ZnO composites against rhodamine B and rhodamine 6G
Fibers and Polymers, 2015The 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.

New uncatalysed bromate-driven oscillators: The Rhodamine B base/Rhodamine B−BrO−3−H2SO4 systems
Proceedings / Indian Academy of Sciences, 1993New uncatalysed chemical oscillations have been found in the Rhodamine B base−BrO 3 − −H2SO4 and Rhodamine B−BrO 3 − −H2SO4 systems in a batch reactor. A non-oscillating absorption band due to an intermediate species was isolated, which is anticipated to have close relationship with the one-electron redox couple of these dye oscillators.

Aggregation of Rhodamine B in Water
Russian Journal of Applied Chemistry, 2004Protolytic and associative equilibria in aqueous solutions of rhodamine B were studied. The curves of potentiometric titration with NaOH solution of the dye hydrochloride within the 5 ×10-4-3 ×10-2 M range and at an ionic strength of 0.1 M (NaCl or KCl) were treated by chemometric methods of successive modification of the equilibrium system models with

Electrochemical Degradation of Rhodamine B Dye
2016The demand of water doubles globally due to rapid increase in population and industrial activities. With the development of dye industries, the dye waste water has become one of the important environmental problem. In order to evaluate the feasibility of removal of basic dye Rhodamine B from aqueous solution, the electrolysis of aqueous solution of dye

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.

Rhodamine B surface state hole traps
Surface Science, 1980Abstract In this paper, the surface photovoltage of Rhodamine B is measured and 5800 A laser pulse (1028 photons cm−2 s−1) incident on the film produced a 2.02 μV photovoltage signal which decayed exponentially with a 9.01 msec relaxation time. The Rhodamine B surface had an accumulation space charge layer resulting from the presence of surface ...

Photophysics of Rhodamine B Interacting with Silver Spheroids
Journal of Colloid and Interface Science, 1999Deactivation processes of Rhodamine B (RB) in water and interacting with silver sols were studied by using conventional fluorescence, laser-induced fluorescence, and pulsed laser photoacoustics. Results showed that the emission efficiencies, absorption cross sections, and nonradiative deactivation pathway of RB interacting with silver spheroids of ...
