The photoluminescent properties of nanocomposite materials on the base of polyvinylidene fluoride (PVDF) with filler ZnS were researched in the range λ=300−1000 nm. As matrixes was used powder PVDF with size of the particles 0.5−1.0 micrometer. It Is Shown that with increase the concentrations source solution sizes nanoparticales ZnS in PVDF increase, i.e. in process of the shaping clusters occur the merging nanoparticales ZnS in the centre of the crystallizations of the nucleation. There was also installed that for nanocomposites exists the offset of the bands to luminescence in short-wave side at reduction of the concentrations nanoparticle in matrix and, consequently, size. This can be explained as absorption luminescence in optical thick diffusing sample, so and change its spectral composition.
