摘要:

适宜的金属离子与荧光团的距离是获得高效荧光强度的关键,但对二者距离的调控通常比较繁琐。针对此问题,本文采用铜网上的碳膜充当金属银与荧光团之间的隔离层,利用硝酸银AgNO3与铜网之间发生置换反应以制备得到负载在铜网上的银/十二烷基硫酸钠(Ag/SDS) nested-network结构,获得了高效的荧光增强效果。

关键词: Ag/SDS nested-network, 铜网, 碳膜, 荧光强度

Abstract:

Appropriate distance between metal ions and fluorophore is the key to obtain high fluorescence intensity, while the tuning of the appropriate distance between them is fussy. In this paper, the carbon film of copper mesh was firstly used as the isolation layer between Ag and fluorophore, displacement reaction between AgNO3 and copper mesh was used to prepare copper mesh loading Ag/SDS nested-network, which exhibits efficient fluorescence enhancement effect.

Key words: Ag/SDS nested-network, copper mesh, carbon film, fluorescence intensity
