摘要：

Molybdenum-containing composite nanomaterials are synthesized by the thermal decomposition of molybdenum hexacarbonyl in a solution-melt of polyethylene in mineral oil. The concentration of a metal-containing filler in the composite materials varied from 1 to 20 wt %. A technique for preparing film samples for spectroscopic studies is developed, and the samples obtained are studied by UV, IR, and Raman spectroscopy. It is found that additional absorption bands appear in the IR range, whose intensity depends on the concentration of molybdenum-containing nanoparticles in the composite materials. The spectral characteristics of Raman scattering show that all samples are characterized by the stretching of the C-C bond. In the visible light region, the spectrum of nanocomposites has a flat edge of its own absorption located in the region of wave numbers (18-31) x 10(3) cm(-1).
