| 摘要: 通过微乳液法及其辅助的溶剂热法制备出了不同形貌的SrMoO4粉体材料，探讨了工艺参数对SrMoO4材料形貌的影响。微乳液体系中表面活性剂十六烷基三甲基溴化铵(CTAB)浓度、反应物浓度及溶剂热过程中反应时间、CTAB浓度都会对SrMoO4材料的形貌造成影响。通过调整上述工艺参数可以调控SrMoO4材料的形貌，得到了近球状、哑铃状、纺锤体状、花簇状等特殊形貌的SrMoO4微晶材料。SrMoO4样品的室温光致发光谱是由发光中心在约420 nm处的单一紫光组成，样品的形貌不同发光强度和发光峰位置略有不同。 |

| Abstract: SrMoO4 powders with different morphologies were prepared via microemulsion and solvothermal methods. The effect of process parameters on the morphology of the SrMoO4 products was investigated. The results show that CTAB content and reactant concentration in the microemulsion system, the reaction time and CTAB concentration in solvotheraml process have great influence on the morphology of the SrMoO4 products. By adjusting the above process parameters, we can control the morphologies of products then obtain special morphologies of the SrMoO4 products, such as sphere, dumbbell, spindle and flower cluster like. The strong single violet emission centering at about 420 nm was observed in the room temperature PL spectra of the SrMoO4 samples. The luminous intensity and peak position were different for the samples with different morphologies. |
