Abstract

The photoluminescence spectra of compositions are investigated on the basis of thermoplastic polymers and semiconductor filler of CaGa₂S₄:Eu at the range of wavelength λ=350÷700 nm. Is shown, that the photoluminwscence spectra depend on the volume contents of filler, polarity of polymer and from the condition of electrothermopolarization. It is supposed, that the observable changes of spectrum are connected to energy of activation, process of overlapping of polymer with filler and change supermolecular structure of polymers and excitation in the CaGa₂S₄:Eu the new luminescent centers.
