摘要：
In the given paper were investigated photoluminescence properties of PVDF/PbS/CdS hybrid nanocomposites after thermal treatment at different temperatures (100 degrees C, 120 degrees C and 140 degrees C) under the vacuum. The optical band gap was calculated on the basis of the spectra of UV absorption and it was shown that after thermal treatment the nanocomposites optical band gap changed. The change has been attributed to the modification of the upper molecular structure of the polymer matrix due to the thermal process. The luminescence spectra of nanocomposites before and after thermal treatment at different temperatures (100 degrees C, 120 degrees C and 140 degrees C) under vacuum were also measured and discussed. It was found that the reduction of the luminescence spectra of nanocomposites after thermal treatment at high temperatures is due to the increase of the intermolecular interactions between the nanoparticles and the matrix due to the removal of the solvent from the polymer and the change in the polymeric structure.
