为了提高钙钛矿纳米晶CsPb,X,3,(,X,=Cl, Br, I)在水或热等环境中的稳定性,本文采用热注射法合成了3‐氨丙基‐三乙氧基硅烷(APTES)修饰的CsPbBr,3,纳米晶,在此基础上,以正硅酸四甲基酯(TMOS)为硅源制备了CsPbBr,3,@SiO,2,核壳结构纳米颗粒。通过X射线衍射、透射电子显微镜和荧光光谱仪等测试手段对样品的结构、形貌、光谱特性及稳定性等进行了分析。结果表明,CsPbBr,3,纳米晶表面形成了SiO,2,壳层,同时,CsPbBr,3,@SiO,2,纳米颗粒仍保持优异的光学性能。更重要的是,SiO,2,壳层显著提高了CsPbBr,3,的水、热稳定性,CsPbBr,3,@SiO,2,在60 ℃加热30 min后发光强度可以保持初始强度的81%,浸水100 min后发光强度仍保持初始强度的75.2%。此外,我们设计了CsPbBr,3,@SiO,2,‐聚二甲基硅氧烷(PDMS)复合薄膜,实现了CsPbBr,3,@SiO,2,在柔性显示与荧光防伪方面的应用,有望为柔性显示和荧光防伪材料的开发提供参考。
To improve the stabilities of all-inorganic perovskite nanocrystals(NCs) CsPb,X,3,(,X,=Cl, Br, I) under water or thermal conditions, 3-aminopropyl-triethoxysilane(APTES) modified CsPbBr,3, NCs were synthesized by a hot-injection method, and then CsPbBr,3,@SiO,2, core-shell nanoparticles(NPs) were prepared by using tetramethyl orthosilicate(TMOS) as silicon source. The structures, morphologies, optical properties and stabilities of the CsPbBr,3,@SiO,2, samples were characterized and analyzed by X-ray diffractions, transmission electron microscopy and fluorescence spectrometer. The results show that the SiO,2, shell forms uniformly on surface of CsPbBr,3, NCs, which still shows excellent optical properties. More importantly, the stabilities of CsPbBr,3,@SiO,2, NPs are significantly improved in water or thermal atmosphere. The photoluminescence intensity of CsPbBr,3,@SiO,2, remains 81% under heated at 60 ℃ for 30 min, and it remains 75.2% when mixed with water for 100 min. Furthermore, we fabricated CsPbBr,3,@SiO,2,-polydimethylsiloxane(PDMS) composite films to explore the applications of CsPbBr,3,@SiO,2, in the field of flexible display and fluorescent anti-counterfeiting.
