Abstract
The excitation and photoluminescence spectra of composites based on PVDF and filler CaGa2S4:Eu2+ were not measured at room temperature. The photoluminescence spectra were analyzed at different concentrations of Eu2+ ions and it was found that the position of the maximum of the PL spectra does not change with an increase in the content of Eu2+ ions in the compound, and the maximum of the PL spectrum in all percentages is ~550 nm with the electronic transition 4f 65d1 → 4f 75d.
