Poly(vinylidenefluoride) film (PVDF) doped with Eu(III) (NO3)3 (o-Phenanthroline)2 complex (complex A) was manufactured using an extrusion technique. Emission spectrum of the film was compared to spectra of the dopant and polyethylene based film. Stretching the film resulted in a sharp growth of intensity and spectral shifting and reshaping of the luminescence spectrum. The impact of the PVDF matrix on the photoluminescence spectra of the complex A is attributed to the Stark effect. Reasons for the increase of luminescence intensity are discussed. The amplification and frequency shifting of the luminescent spectrum of europium-complex-doped PVDF may lead to promising applications.
