   The photoluminescence spectra of compositions are investigated on the basis of thermoplastic polymers and semiconductor filler of CaGa2S4:Eu at the range of wavelength l=350—700 nm. Is shown, that observable changes on the spectra for compositions at excitation by the pulse laser depending on the volume contents, electrothermopolarization and polarity of polymer, apparently, are connected to change supermolecular structure of polymers, degree of interaction of polymer with filler, and also from absorption energy of quantum of composites, mobility of polymer macromoleculs therefore apparenty is increased, there is excitation in the CaGa2S4:Eu luminophorous the new additional luminescent centres.
