Abstract
The excitation and photoluminescence spectra of composites based on PVDF and filler have been measured at room temperature. The photoluminescence spectra were analyzed at different concentrations of Eu2+ ions. It was found out that positions of PL spectra maxima do not change with an increase in the content of Eu2+ ions in the compound and remain ~ 550 nm at all percentages. Radiation with such a maximum is caused by the 4f65d1-> 4f75d electronic transition. Keywords: photoluminescence, excitation, rare earth element, phosphor, europium.
