Abstract

The organic-inorganic materials with fluorescence properties are synthesized in the form of gels and xerogels from tetraethoxysilane and glycidoxypropyltrimethoxysilane by the sol-gel method. The concentration of the introduced Nile Red dye is 2.2 × 10−6 M. The fluorescence spectra of the prepared materials are measured and analyzed as a function of the ratio between the initial components forming the sol-gel epoxy siloxane matrices. The assumption regarding the structure of the synthesized hybrids is made invoking the data obtained by Fourier-transform IR spectroscopy and atomic-force microscopy.
