SYNTHESIZE, STRUCTURE AND LUMINESCENCE PROPERTIES OF NANOPARTICLES BaMoO4 DOPED Eu3+ BY HYDROTHERMAL METHOD

Abstract

The article shows the results of studying the characteristic properties and luminescence of nanomaterials BaMoO₄ doped Eu³⁺ (BME). BME nanoparticles (doped 0.1 to 9.0 mol% Eu³⁺) have been successfully synthesized by hydrothermal method. The results of structural study through the X-Ray Diffraction (XRD) showed that the single-phase crystalline BME material was consistent with the tetragonal structure of BaMoO₄ (according to JCPDS card no. 00-029-0193).  The characteristic bonding groups of Eu-O, Mo-O and MoO₄^2- confirmed by Raman spectroscopy demonstrated the successful doping of Eu³⁺ ions into the matrix lattice. The Field Emission - Scanning Electron Microscope (FE-SEM) images show that the BME material has a relatively uniform nanoparticle size. The diameter is between 19.57 nm and 39.62 nm. The Fluorescence spectrum shows that BME materials have the ability to fluoresce red with great intensity at about 616 nm, corresponding to the ⁵D₀ → ⁷F₂ transition. With superior properties in morphology, structure and red light emitting source, BME nanomaterials have potential of applications in manufacturing white and warm LED light with low energy consumption.
