Facile route for synthesis of strontium hexaborate crystalline powders

Abstract

In this paper, a solid‐state reaction route was developed to synthesize SrB6O10 crystalline powders. Regarding the last preparation methods, a short process time of synthesis was achieved that has not reported before. The prepared sample was characterized using various methods, such as X‐ray diffraction, Raman spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and diffuse reflection spectroscopy. The obtained results proved that the prepared sample at temperature 840°C with 2.5 h duration consists of SrB6O10 crystalline powders with 4.96 eV bandgap.

Efficient route for preparation of Nd3+ doped Y2O3 nanoparticles at intermediate temperature

“…Also, this process is simple, has high yield, high selectivity, and less pollution. It must be noted that the solid-state process is very slow, needs a lot of energy, and occurs at high temperatures [ [36] , [37] , [38] , [39] , [40] ]. In this article, for the first time, an optimized solid-state process for Nd 3+ -doped yttrium oxide nanoparticles was developed at a much lower temperature and in less time than other reported procedures, and then their optical and structural properties were characterized by various methods such as X-ray diffraction, Fourier transform infrared (FTIR), field emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Energy-dispersive X-ray analysis (EDAX) and Selected Area Electron Diffraction (SAED) pattern.…”
