A new procedure is described for the determination of Hg2+ ions in water samples. Rhodamine based fluorescent sensor was synthesized and experimental conditions were specifically optimized application to environmental samples, which requires low detection limits high selectivity competitive experiments with realistic concentrations other metal ions. Incorporation a Rhodamine-6G fluorophore prev...

The spectral characteristics of the fluorescence Rhodamine 6G (Rh6G) molecules doped into different layers one-dimensional photonic crystals (PCs) have been studied at various detection angles. PCs differ in position band gap (PBG) with respect to Rh6G luminescence spectrum. A computation method density PC`s electromagnetic modes proposed. and computed relative versus wavelength compared for ex...

The present investigation aims to synthesize the novel nanocomposite thin film and utilize material remove emerging dyes efficiently (i.e., Rhodamine B (R-B) 6G (R-6G)), in an aqueous solution using LED visible light UV-A light. A facile synthetic route was adopted obtain TiO<sub>2</sub>-supported bentonite <i>in situ</i> decorated with Au nanoparticles (NPs) film. advan...
