有机无机杂化钙钛矿材料由于在光伏领域优异的性能成为了最近的研究热点,但是这一材料遇水分解稳定性差限制了材料的实际应用。我们通过后处理的方式将有机无机杂化钙钛矿材料嵌入到聚合物中,增强了钙钛矿材料的水稳定性。通过共混的方式,无需清洗纳米颗粒,即可获得钙钛矿良好分散性。尽管这一共混材料中钙钛矿表面存在溴空位,但是聚甲基丙烯酸甲酯的加入钝化了钙钛矿的表面,使得钙钛矿减少了缺陷,增加了荧光寿命。同时,这一共混材料良好的颜色纯度和聚甲基丙烯酸甲酯本身具有的良好透过率,为钙钛矿应用到实际的光子器件中提供了可能。
Organic-inorganic hybrid perovskite materials have recently become the focus of research due to their excellent performance in the photovoltaic field, but the poor stability of this material limits the practical application of the material. We embed the organic-inorganic hybrid perovskite into the polymer by post-treatment, which enhances the water stability of the perovskite material. By means of blending, good dispersibility of perovskite can be obtained without washing the nanoparticles. Despite the presence of bromine vacancies in the perovskite surface in this blend, the addition of polymethyl methacrylate inactivates the perovskite surface, reducing perovskite defects and increasing fluorescence lifetime. At the same time, the good color purity of the blend and the good permeability of polymethylmethacrylate itself provide the possibility of applying perovskites to practical photonic devices.
