Abstract
Raman spectroscopic studies were carried out for hybrid polymer thin
films prepared for photonic
applications by the sol-gel technology. Our aims were to analyse the
ability of the Raman method to
estimate the efficiency of the main reactions of the sol-gel process and
to provide information about the
chemical composition of the films as well as their thickness, profile,
and quality. The difficulties in measurement such as low level of Raman
signals, difficulties in data analysis caused by the complex structure
of the materials, and the influence of interfering signals, are
discussed. The application of Raman microscopy
for characterising films based on 3-glycidoxypropyl-trimethoxysilane
(GPTS), methacryloxypropyltrimethoxysilane
(MPTS), and 3-aminopropyl-trimethoxysilane (APTES) is presented. The
efficiencies of
reactions of inorganic and organic polymerisation were measured and
their products have been identified.
The influence of the excitation beam wavelength as well as the type of
substrate on the Raman spectra
was investigated. Moreover, two-dimensional Raman mapping enabled us to
record the thickness profiles
of the deposited structures and to detect their defects.
