- Thermal lens spectrometry is applied to determine the absorption of transparent nanocomposite materials, which are produced by the thermal decomposition of silver salts absorbed in the bulk of a polymethacrylate matrix. The high spatial resolution of determination, corresponding to the size of laser beams, makes it possible to evaluate the homogeneity for the distribution of coloration in the matrix. The advantages of thermal lens spectrometry over spectrophotometry include the weak effect of sample scattering on the results of its absorption determination and a higher sensitivity of determination, which may exceed that of spectrophotometry by one or two orders of magnitude. The possibility of achieving local syntheses of nanosized particles in the bulk of the matrix by virtue of the photoinduced decomposition of silver salts in initial polyacrylate materials is shown. Thermal lens experiments also allow the combination of the synthesis of silver nanoparticles and control of the absorbance for the prepared structural units.
