钙钛矿结构CH3NH3PbBr3纳米线的制备方法
摘要：
本发明公开了钙钛矿结构CH3NH3PbBr3纳米线的制备方法，包括制备CH3NH3PbBr3的有机溶剂溶液，将CH3NH3PbBr3的有机溶剂溶液铺展在基底的亲水性表面进行有机溶剂的挥发；挥发有机溶剂后的基底再进行退火处理即得CH3NH3PbBr3纳米线。本发明采用溶剂挥发与退火技术结合进行CH3NH3PbBr3纳米线的制备，通过发现在重力及液体表面张力的共同作用下，随着溶剂的挥发，溶质在析晶过程中，会趋向于生长为一维结构的现象，成功的制备出了纳米线的结构，不仅制备工艺简单，且通过不同溶质的含量的控制实现了可控尺寸进行纳米线生长的目的。
摘要（英）：

The invention discloses a method for preparing a perovskite structure CH3NH3PbBr3 nano-wire. The method comprises the following steps: preparing a CH3NH3PbBr3 organic solvent solution; spreading the CH3NH3PbBr3 organic solvent solution on a hydrophilic surface of a substrate to volatize the organic solvent; and annealing the substrate after the organic solvent is volatilized to obtain the CH3NH3PbBr3 nano-wire. According to the method, the CH3NH3PbBr3 nano-wire is prepared by combining solvent volatilization technologies, solute tends to a phenomenon of growing a one-dimensional structure along with volatilization of the solvent in the crystallizing process under common effect of gravity and liquid surface tension, and the structure of the nano-wire is successfully prepared. The preparation process is simple, and the aim of nano-wire growth with controllable growth can be achieved by controlling the content of different solutes.
