Abstract
Development of a simple sol-gel-based method for producing high quality mesostructured hybrid films within different concentration Rhodamine 6G is reported. Dip coating or spin coating methods were using for film casting with different optical characteristics. The films have been characterized by UV-Vis absorption spectroscopy and excitation fluorescence spectroscopy. The observed manifold of the optical and fluorescence spectra shows the ability of controlled aggregation of dye molecules owing to time delay of their spontaneous transformation during the process of formation of mesostructured hybrid sol-gel films. Preliminary experiments have shown viability of the composite films for excitation of lasing that is perspective for design of waveguide nanolasers.
