| Abstract: | The conversion of J-aggregates to H-aggregates in composite materials (organic dye-inorganic substrate) was firstly obtained in the experiment.We also observed that the laser illumination can lead to fluorescence quenching in composite materials.The temporal changes in spectra of highly ordered nanocomposite arrays(Rh6G-AAO) induced by laser illumination,which are formed by filling anodized aluminum oxide(AAO) with Rhodamine 6G(Rh6G) dyes,were studied by visible absorptive and fluorescent spectr... |
