摘要

SrMoO₄ crystallites with varying morphology have been prepared by the chemical reaction of strontium chloride and sodium molybdate in a reverse microemulsion system consisting of water, OP (p-octyl polyethylene glycol phenylether, non-ionic surfactant), 1-pentanol (co-surfactant) and cyclohexane (oil). The resultant powders were characterized in detail by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and photoluminescent spectra techniques (PL), respectively. It was found that SrMoO₄ crystallites with different morphologies could be synthesized by the microemulsion process with different aging times. PL spectra showed that the spindle-shape SrMoO₄ crystallites with a higher aspect ratio resulted in better photoluminescence property.
