Physical And Chemical

The science of core-shell nanoparticles requires investigation into several physical and chemical properties of the composite nanoparticles. Unlike the conventional sol-gel or the reverse microemulsion micelle method, we presented here a non-seeded process of encapsulating superparamagnetic magnetite nanoparticles (SPMN) with silica. Physico-chemical analysis of the product was used to confirm the result of the coating procedure. Colloidal suspension of SPMN and silica nanoparticles were synthesised through coprecipitation method and modified Stöber method respectively. Afterwards, both colloidal suspensions of SPMN and silica nanoparticles were sonicated to encapsulate the SPMN with silica. Elemental mapping of the composite particles with electron spectroscopy imaging (ESI) confirmed the core-shell micrograph of the SPMN and silica. The X-ray diffraction pattern (XRD) showed the silica shell to be in amorphous form. FTIR analysis further confirmed the chemical properties of the product to be silica coated SPMN.

Core-shell nanoparticles Gd2O3:Tb3+/SiOx were obtained by encapsulating Gd2O3:Tb3+ in a polysiloxane shell. We studied the influence of two kinds of reagents (NaOH and Bu4NOH) reacting with precursor solution on size and luminescent property of nanoparticles. The result showed that the reaction involving NaOH was more favorable to the growth of nanoparticles, thus enhanced the energy transfer between the core and the shell of particles and improved their luminescent intensities.
