摘要
碳点(Carbon dots,CDs)具有制备简单、来源广泛、毒性低和光学性能优异等特性,可作为发光材料应用于固态照明器件中。基于CDs荧光薄膜的制备及实现其白光发射的方式不同,使其白光荧光薄膜的性能各异。首先,介绍了CDs的光致发光机制;其次,根据CDs荧光薄膜的形成方式归纳为CDs/聚合物荧光薄膜和CDs自组装荧光薄膜两类,并介绍其制备方法;然后,根据荧光薄膜中所含荧光材料的种类,将实现荧光薄膜白光发射的方式概括为两种:混合多色荧光材料和使用单一白光CDs;最后,提出白光CDs及其荧光薄膜目前存在的问题,并展望其进一步的发展。
Carbon dots(CDs)have many excellent characteristics,including simple preparation,abundant sources,low toxicity and excellent optical properties,that can be served as fluorescent materials to prepare fluorescent films for solid-state lighting devices.The different ways of the CDs-based film formation and their white light emission make the variety properties of fluorescent films.Firstly,the photoluminescence mechanisms of CDs are introduced.Secondly,the fluorescent films are divided into two categories based on the film formations:CDs/polymer fluorescent films and CDs self-assembled fluorescent films,and their preparation methods are summarized.Thirdly,according to the types of fluorescent materials in the fluorescent film,two means of realizing white light emission of fluorescent films are introduced by mixing polychromatic fluorescent materials and using single white light CDs.Finally,the problems of CDs and their fluorescent films and the prospects for development of CDs-based fluorescent films are discussed.
