Preparation, characterization, and luminescence of host (Y zeolite)–guest (FeS, CoS, NiS) nanocomposite materials

The host–guest nanocomposites (Y zeolite)–sulfides (FeS, CoS, NiS) were successfully prepared by a hydrothermal method and characterized by powder XRD, chemical analysis, adsorption technique, infrared spectroscopy and X-ray photoelectron spectroscopy. The Y zeolite–NiS host–guest nanocomposite material was found to exhibit luminescence. This paper suggests that the luminescence mechanism of Y–NiS resulted from the excitons in the confinement areas and from the defects in the materials. The material Y–NiS may be used as luminescent materials.
