SYNTHESIS AND STUDY ON THE CHARACTERISTICS OF NANOMATERIALS BAMoO4 CO-DOPED Eu3+, Mn2+ BY HYDROTHERMAL METHOD

Abstract

This article presents the structural and morphological characteristics of the nanomaterials BaMoO₄ co-doped Eu³⁺, Mn²⁺ (BMEM) which have been successfully synthesized by hydrothermal method. The X-ray diffraction (XRD) shows that the materials BMEM have single-phase crystals and are consistent with the tetrahedral structure of BaMoO₄ (according to JCPDS tag number 029-0193). The characteristic modes and bonding groups of Mo-O, Eu-O, Mn-O and MoO₄^2- confirmed by Raman spectroscopy demonstrated the successful co-doped of Eu³⁺ and Mn²⁺ into the host lattice. The EDS spectra confirmed the composition, purity and uniformly distributed density of Eu, Mn, Ba, Mo, O elements in the host matrix. The field emission - scanning electron microscope (FE-SEM) and transmission electron microscope (TEM) images show that the materials BMEM have a relatively uniform nanoparticle size, which is less than 50 nm. Nanomaterials BMEM have outstanding properties in terms of morphology, structure and purity, and have potential applications for white light emitting diodes.
