Preparation and Application of Inorganic Persistent Luminescent Composite Materials

长余辉材料是一种特殊光致发光材料,能在光照时储存能量,并在移除光源时以光的形式缓慢释放能量。其中无机长余辉材料因其独特的长时间余辉发光特点,而在数据存储、信息技术、照明、光催化和生物医学等多个领域发挥着重要作用。为了改善无机长余辉材料的各种性能和功能,研究人员研发了基于无机长余辉材料的多功能复合材料。本文结合有关无机长余辉复合材料的报道和本课题组的研究成果,总结了无机长余辉复合材料的制备方法,重点介绍了无机长余辉复合材料在光催化、生物医药、防伪加密等方面的研究和应用进展,并展望了其在实际应用中面临的机遇与挑战。

Persistent luminescent materials are photoluminescent materials that store energy when exposed to light and slowly release it as light when the light source is removed.Among them,the inorganic persistent luminescent materials because of its unique characteristics of long afterglow luminescence that make them useful in various fields,including data storage,information technology,photocatalysis,and biomedicine.Researchers have developed multifunctional composites based on inorganic persistent luminescent materials to enhance their properties and functions.However,there is still a lack of a systematic and comprehensive review of inorganic persistent luminescent composite materials.This paper summarizes the preparation methods of inorganic persistent luminescent composites,combining recent literature reports on inorganic persistent luminescent composites and the research work of our group,and then focuses on the progress of the research and application of inorganic persistent luminescent composites in photocatalysis,biomedicine and anti-counterfeiting.Finally,the opportunities and challenges for the practical application of inorganic persistent luminescent composites are analyzed from a prospective point of view.
