    摘要:

    基于有机荧光染料的固体团聚或者堆叠导致荧光猝灭、发光和稳定性减弱,采用剥离与超分子组装的方法,制备固体荧光超薄膜发光体。首先通过剪切剥离制备蛭石纳米片,控制其粒径分布在30~300 nm,再通过与有机荧光染料(罗丹明6G和罗丹明B)层层超分子组装的方法,获得蛭石有机无机荧光薄膜。经对比实验发现,不添加蛭石纳米片,无法获得均匀发光的荧光薄膜。蛭石有机无机荧光薄膜的SEM显示,有机荧光染料和蛭石分布均匀,克服有机荧光染料团聚或者堆叠的荧光猝灭,实现荧光亮度可控。

    Abstract:

    Based on solid agglomeration or stacking of organic fluorescent dyes, which leads to fluorescence quenching, luminescence, and weakening of stability, the method of exfoliation and supramolecular assembly is used to prepare solid fluorescent ultra-thin film emitters. First, vermiculite nanosheets were prepared by shear exfoliation, and their particle size distribution was controlled at 30-300 nm. Then, vermiculite organic-inorganic vermiculite was obtained by layer-by-layer supramolecular assembly with organic fluorescent dyes (rhodamine 6G and rhodamine B). fluorescent film. It was found by comparative experiments that a uniform luminescent fluorescent film could not be obtained without adding vermiculite nanosheets. The SEM of the vermiculite organic-inorganic fluorescent film shows that the organic fluorescent dyes and vermiculite are evenly distributed, which overcomes the fluorescence quenching of the agglomeration or stacking of the organic fluorescent dyes, and realizes the controllable fluorescence brightness.
