Abstract (SnO2)1-x (NiFe2O4)x (x = 0, 0.85, 0.7, 1) nanocomposites were synthesized by a three-step hydrothermal technique. The crystal structure and morphological variations of SnO2/NiFe2O4 nanocomposites were investigated provided the results of x-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), and field emission scanning electron microscopy (FESEM). The composite oxide materials having well-dispersed phases of nanocrystalline nature from together the pristine tin oxide with the tetragonal rutile phase and the spinel cubic structure of nickel ferrite. Growths of remarkable nanorods (diameter 13.79 and length 150.64) of high facet ratio are detected along with nano-octahedrons, nanoparticles and porous hallow nanocube of 30SnO2–70NFO nanocomposites. With the rise of the contents of NiFe2O4 the capability of SnO2/NiFe2O4 nanocomposites for absorption within the visible domain became significantly stronger and revealed a red-shift within the visible-light area that confirms by diffuse reflectance spectroscopy (DRS), and photoluminescence (PL) spectroscopy. The nanocomposite SnO2/NiFe2O4 confirms a better magnetic response toward an external magnetic field that verifies by vibrating sample magnetometer (VSM). Eventually from optical and magnetic descriptions; well-supporting results in favor of photoinduced charge immigration and magnetic segregation were accomplished for nanocomposites.
