摘要：
Optimal technological conditions for the fabrication of nanocomposite films based on the poly(di-n-hexylsilane) (PDHS) incorporated into a TiO2 nanoporous film have been developed, and such composites are fabricated. Their optical spectra have been investigated in a wide temperature range (15-330) K. It is shown that the distinctive feature of nanocomposite films is related to the predominant fluorescence band of aggregates with respect to the fluorescence bands corresponding to the gauche- and transconformations of polymer chains and to the observation of the intense fluorescence band of aggregates even at room temperature.
