Abstract The magnetic and optical properties of polycarbonate (PC)/Fe nanocomposite films prepared by a solution blended process and the role of Fe additives are investigated. The saturation magnetization of the PC/Fe nanocomposites depends on the weight of Fe nanoparticles. Meanwhile, an increase of photoluminescence (PL) intensity with decreasing Fe additives is interpreted. The optical band gap corresponds to the increase of PL elements. The transmittance of the films increases with reduced Fe, and the PL peak energy of PC/Fe composites is also correlated to the weight ratio.
