Plasmons have facilitated diverse analytical applications due to the boosting signal detectability by hot spots. In practical applications, it is crucial fabricate straightforward, large-scale, and reproducible plasmonic substrates. Dewetting treatment, via applying direct thermal annealing of metal films, has been used as a straightforward method in fabrication such nanostructures. However, tailoring evolution dewetting process films poses considerable experimental complexities, mainly nanoscale structure formation.
