Synthesis of hexagonal YMnO3 nanoparticles by sol-gel route and their characterization

Abstract

Hexagonal yttrium manganese oxide (h-YMnO₃) nanoparticles were prepared by a modified citrate sol-gel process at a lower heating temperature (200^oC-230^oC) followed by grinding and calcination. The structure and morphology of the synthesized nanoparticles were studied using an X-ray diffraction (XRD) technique and scanning electron microscope (SEM). _YMnO3 nanoparticles with a uniform micro structure were observed in SEM images. The XRD analysis showed that the prepared precursor powder was well crystallized. The elemental compositional analysis using energy-dispersive X-ray analysis (EDX) confirmed the elemental base composition of pure yttrium, manganese, and oxygen.
