Title (EN) FLUORESCENT PEROVSKITE NANOCRYSTAL AND CONFIDENTIAL INFORMATION SECURITY APPLICATION THEREOF
(FR) NANOCRISTAL DE PÉROVSKITE FLUORESCENT ET SON APPLICATION EN SÉCURITÉ D’INFORMATIONS CONFIDENTIELLES
(ZH) 荧光钙钛矿纳米晶的制备方法及在机密信息安全中的应用
Abstract:
(EN) A method for preparing a fluorescent perovskite nanocrystal and an application thereof for confidential information storage and protection. A cationic halogenated salt solution for use in synthesis of perovskite is added to a metal organic framework dispersion, to directly convert a metal organic framework part into a fluorescent perovskite nanocrystal, and uniformly disperse the fluorescent perovskite nanocrystal in the metal organic framework crystal, thereby providing desirable fluorescence performance. The method has broad applicability. The synthesis method for a perovskite nanocrystal can be directly used in storage and protection of confidential information. Compared with the prior art, the operation process is simple and repeatable, and the metal organic framework material and recorded information thereof are highly secure. The fluorescent perovskite nanocrystal has no absorption in the visible light range, has fluorescent properties, and is invisible to the naked eye. The perovskite nanocrystal has good fluorescent properties, allowing it to be directly applicable to the field of confidential information storage and protection.
(FR) La présente invention concerne un procédé de préparation d’un nanocristal de pérovskite fluorescent et son application pour le stockage et la protection d’informations confidentielles. Une solution de sel halogénée cationique pour l’utilisation dans la synthèse de pérovskite est ajoutée à une dispersion de structure organique métallique, pour convertir directement une partie structure organique métallique en un nanocristal de pérovskite fluorescent, et disperser uniformément le nanocristal de pérovskite fluorescent dans le cristal à structure organique métallique, fournissant ainsi une performance de fluorescence souhaitable. Le procédé présente une large applicabilité. Le procédé de synthèse d’un nanocristal de pérovskite peut être directement utilisé dans le stockage et la protection d’informations confidentielles. Comparé à l’état de la technique, le procédé de fonctionnement est simple et peut être répété, et le matériau à structure organique métallique et son information enregistrée sont hautement sécurisés. Le nanocristal de pérovskite fluorescent ne présente pas d’absorption dans la plage de la lumière visible, présente des propriétés de fluorescence, et est invisible à l’œil nu. Le nanocristal de pérovskite présente de bonnes propriétés de fluorescence, lui permettant d’être directement applicable au domaine du stockage et de la protection d’informations confidentielles.
(ZH) 一种荧光钙钛矿纳米晶的制备方法和在机密信息储存和保护中的应用。将用于钙钛矿合成的阳离子卤化盐溶液加入到金属有机骨架分散液中,直接使金属有机骨架部分转化为荧光钙钛矿纳米晶,均匀地分散在金属有机骨架晶体中,具有很好的荧光性能,该方法具有通用性。钙钛矿纳米晶的合成方法可直接用于机密信息的储存与保护。与现有技术相比,操作过程简单可重复、金属有机骨架材料及其记录的信息非常安全,可见光范围内无吸收,具有荧光特性,不能够被肉眼识别。钙钛矿纳米晶荧光特性良好,使其直接能在机密信息储存与保护领域中应用。
