摘要/Abstract

摘要： 以海藻酸钠(alginate,Alg)为基质,引入镧系元素(lanthanides,Ln)和碳点(carbon dots,CDs)为发射中心,采用注射法成功制备了两种双发射凝胶球(Ln@CDs@Alg,Ln=Eu、Tb),并对其结构和荧光性能进行了表征.结果表明,Ln@CDs@Alg凝胶球在254 nm紫外光(ultraviolet,UV)激发下分别发射红色、绿色荧光,在365 nm紫外光激发下发射蓝色荧光.基于该特性,设计了一种防伪阵列,即在365 nm紫外光激发下显示的蓝色荧光用于信息保护,254 nm紫外光激发下显示由红色、绿色荧光组成的信息“MY”.该凝胶球阵列展现的双波双色多级保护特性,在防伪领域具有广阔的应用前景.

Abstract: Dual-emission gel spheres（lanthanides（Ln）@carbon dots（CDs）@alginate（Alg）,Ln = Eu, Tb） were successfully prepared using a simple injection method, with Alg as the matrix and Ln and CDs as emission centers. Furthermore, their structures and luminescent properties were characterized. The results revealed that the Ln@CDs@Alg gel spheres emitted red and green fluorescence under ultraviolet（UV） excitation at 254 nm, and blue fluorescence under UV excitation at 365 nm. Based on this property, an array was developed that displayed blue fluorescence under UV excitation at 365 nm for information protection and revealed the encoded information “MY” in red and green fluorescence under UV excitation at 254 nm. The unique features demonstrated by the gel sphere array presented significant potential for applications in the field of anti-counterfeiting.
