Synthesis and Characterization of Strontium Oxide Nanoparticles via Wet Process

摘要

Strontium Oxide (SrO) nanopowder was synthesized by hydrolysis of single source molecular precursor SrCl_2 • 6H_2O with potassium hydroxide. The structure, morphology and properties of the particle were characterized by XRD, TEM, Raman and UV-vis-spectroscopy. The mean particle size (28.6 nm) was calculated by using X-ray diffraction pattern. A crystalline nature and with controlled particle distribution and phase purity was established with XRD and FT-IR. The crystallite size and phase purity increases with temperature which depends on the molar ratio of the starting molecular precursor, pH, temperature, reaction time along with its synthetic methodology.
