Lead-free ferroelectric materials integrated ferromagnetism and photoluminescence at room temperature. Fe and Sm cations were used as the magnetic and photoluminescence sources for the co-modified host materials. The (Fe, Sm)-modified materials were fabricated by using the sol-gel method. The structure of the samples was studied through X-ray diffraction and Raman scattering, which indicated that a single perovskite structure was successful fabricated. The samples exhibited strong photoluminescence in the visible light range, and complex ferromagnetic properties were obtained. We expect our work to open a new direction in the development of advanced function materials for smart electronic device applications. | Successful combination of ferromagnetism and photoluminescence properties in lead-free ferroelectric materials
