The magnetic and fluorescence properties were studied for a polymer nanocomposite (PNC) based on strontium hexaferrite (Sr-M) nanoparticles embedded in a polyvinyl alcohol (PV–OH) matrix. This study reveals the effect of nanoparticles operating on the structural behavior and the functional properties of the polymer nanocomposite. The X-ray diffraction and the Rietveld method showed a change of the PV-OH semi crystallinity as the number of nanoparticles varies in the composite. This behavior has been related to the close interactions between the nanoparticles and the polymer which show to be capable of modifying the structural and functional properties of the matrix. Here, the nanoparticles promote a fluorescence quenching as the nanoparticles increase. Then, a close relationship between the polymer structure and its functional properties is discernible. Also, the number of nanoparticles and their arrangement in the PNCs promote the emergence of magnetic interactions which change the micromagnetic properties of the system. © 2022 Elsevier B.V.
