In the process, iron oxide particles having a size distribution within 8–19 nm were prepared by using a reverse co-precipitation method followed by the formation of iron oxide-core with silica shell (with 50–150 nm diameter of silica spheres) by using a modified Stöber method. The phase, morphology, optical and magnetic properties of the synthesized powders were characterized by using X-ray diffraction, scanning electron microscope (SEM), transmission electron microscope, UV–visible spectrometer (UV–Vis) and vibrating sample magnetometer. Spherical morphology of the Ag nanoparticles was found to deposit on the iron oxide-silica surfaces. The particle size distribution is depending on the synthesis approach used. The UV–Vis absorption peak at 404–410 nm of wavelength confirmed the existence of the Ag nanoparticles.
