摘要：
This work reports on the robust ferromagnetism at room temperature in co-precipitation derived rare-earth (Tb) and transition metal (Co) co-doped ZnO nanoparticles (NPs). X-ray diffraction (XRD) analysis reveals the singlephase character. Morphological studies confirm the formation of spherical-shaped particles with different orientations separated by well-defined grain boundaries. The increase in oxygen vacancies is confirmed by photoluminescence (PL) spectra. The (Tb, Co) co-doped NPs exhibit room temperature ferromagnetic (RTFM) behavior, which has been discussed based on oxygen vacancies mediated magnetic polarons and the effect of grain boundaries.
