Depending on the selenophene structure and the presence of auxiliary surfactants luminiscent nanoparticles with different form-factor (spherical, elongated, branched) were obtained. The effect of the polymer matrix on the agglomeration of luminescent nanoparticles, their spatial distribution and the spectral and kinetic characteristics of the polymer nanocomposites, as a light convertors for blue LEDs was studied. Polystyrene, polydimethylsiloxane and polymethylmethacrylate were studied as the polymer matrices. Strong aggregation of nanoparticles was found in polymethyl methacrylate and polystyrene, however, alkyl surface stabilizer allows obtainment of homogeneous nanoparticle films in thermally stable polymer - polydimethylsiloxane, which can be used as a "working environment" for nanoparticles in light convertors for blue LEDs.
