Hexamine Assisted Hydrothermal Synthesis of Eu³⁺Activated Na_0.5La_0.5MoO₄Microstructures: Synthesis, Structure and Morphological Investigations

Abstract:

Highly uniform and self-assembled spheroid-like microstructures of Na_0.5La_0.5MoO₄:Eu³⁺were successfully synthesized by hexamine assisted hydrothermal route at 180 °C for 24 hours with neutral pH (7~8). Scanning electron microscope, X-ray diffraction pattern and energy dispersive X-ray analysis were used to characterize the morphology, crystal structure, size, and elements of the particles. It is found that, the particle size was well-controlled by increasing the molar concentration of the chelating agent hexamine. While, irradiating at 395 nm UV light, the emission spectra of micro-spheres shows remarkable characteristic dominance of red emission which is attributed to the transition ⁵D₀⁷F₂. Furthermore, the synthesized homogeneous and well-crystallized Na_0.5La_0.5MoO₄:Eu³⁺microstructures will serve as an excellent phosphor candidate to produce high-quality luminescence for display devices in future.Keywords: Hydrothermal route, hexamine, self-assembly, photoluminescence
