摘要：

Nanocomposites based on organic conjugated copolymer SuperYellow (SY) and silica nanoparticles (O300) were obtained. It was shown that modification of the surface of O300 with diphenylsilane increases the dispersivity of the inorganic nanoparticles and makes the nanocomposite films homogeneous. It was established that spatial confinement of the conjugated macromolecules of SY in the nanocomposites has a significant effect on their spectral characteristics. The nanocomposite films are characterized by the presence of a blue shift of the absorption maximum and by much higher photoluminescence intensity with little change in the CIE color coordinate of the emitted light.
