One Step Synthesis of Europia Nanoparticles via Thermal Decomposition of Europium Propionate Crystals
Eu2O3 nanoparticles were fabricated by thermal decomposition of europium propionate crystals, which can be facilely obtained via crystallization. The decomposition and morphlogy of the crystallized product were characterized by X-ray diffractionmetry (XRD), simultaneous differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) as well as scanning electron microscopy (SEM). The effects of the calcination temperature on the resultant microstructures such as crystallinity, particle size and particle dispersibility were investigated by XRD and transmission electron microscopy (TEM). The results indicated the morphology of the as-calcined products shows transmissibility compared with the precursor and that the calcination temperature of europium propionate is crucial to evolution of the resultant morphology from three-dimensional network of agglomerated nanoparticles to dispersed nanoparticles.
