In this research, cobalt sulfide nanoparticles (NPs) were grown on AlMCM-41 matrix by using ion exchange method. The prepared sample was irradiated by thermalized neutron that emitted from Am–Be source. After that, X-ray diffraction (XRD), UV–vis spectroscopy, Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used for irradiated and non-irradiated samples characterization. The results show the increase of nanoparticles size and aggregation under neutron irradiation. The TEM images show average size of CoS NPs before and after neutron radiation about 20 and 50 nm, respectively. The XRD patterns show that nanoparticles size is increased after neutron radiation. The DRS results show that Co2+ ions produced after neutron radiation, located in tetrahedral sites in AlMCM-41. The results indicate host materials have important role in decrease of radiation defects (RDs).
