Synthesis and Characterization of PbF2 with Wheat-like Morphology |
|
摘要: 用乳液法制备了α-PbF2材料。用粉末X射线衍射(XRD)、透射电子显微镜(TEM)和扫描电子显微镜(SEM)等对所制备产物的结构和形态进行了表征。实验结果表明合成产物的形状为麦粒状, 其直径为400~500 nm,长度为1 500~4 000 nm。产物形貌规整,分散性好,尺寸可控,在室温下有优良的荧光性质。 |

Abstract: PbF2 with wheat-like morphology has been synthesized via a microemulsion route from an aqueous solution of lead acetate and ammonium fluoride. Reaction conditions, such as the concentration of initial reagents and ω, were found to have close relation with the morphologies of final products. The possible formation mechanism has been proposed. Room temperature photoluminescence of PbF2 samples has also been investigated. |
Keywords: α-PbF2 microemulsion luminescence |
