چکیده
|
A two-dimension distributed metallic nanostructure substrate containing two-dimensional array of au nanorods with different configurations is prepared via a self-assembly method. enhanced fluorescence emission with assembled substrate is investigated by employing rhodamine 6g as probe molecule. the experimental observation shows that the prepared nanostructure substrate has strong fluorescence enhancement effect and the enhancement effect critically depends on the configuration of the particle distribution. the study demonstrates that the local electromagnetic field enhancement around the gold nanorod array plays an important role in achieving fluorescence enhancement with the assembled substrate array. this work suggests that the assembled substrate can be considered as a potential candidate for effective enhancement application.
