| 摘 要： | 采用冷却热饱和溶液法,以正丁基碘化胺(BAI)为有机元,碘化铅(PbI2)为无机元来合成二维钙钛矿材料。通过调整BAI与PbI2的配比及反应温度来研究不同因素对所合成钙钛矿产率和结晶质量的影响。利用SEM、XRD、紫外可见吸收及荧光光谱对合成的二维钙钛矿材料进行表征。确定了冷却热饱和溶液法制备二维BA2PbI4的最佳反应条件为,氢碘酸为溶剂,m(BAI)∶m(PbI2)=2.5∶1,水浴加热温度为85℃,水浴时间为120 min。

| Abstract: | The two-dimensional perovskite material was synthesized by using a cooling hot saturated solution method with n-butyl iodide amine(BAI)as an organic element and lead iodide(PbI2)as an inorganic element.The effects of different factors on the yield and crystal quality of the synthesized perovskites were studied by adjusting the ratio of BAI to PbI2 and the reaction temperature.The synthesized two-dimensional perovskite materials were characterized by SEM,XRD,UV-visible absorption and fluorescence spectroscopy.The optimum reaction conditions for the preparation of two-dimensional BA2PbI4 by cooling hot saturated solution method were as follows:with hydriodic acid as solvent,m(BAI)∶m(PbI2)=2.5∶1,water bath heating temperature of 85℃,and water bath time of 120 min. |
