When they drop-cast gold nanoparticles on the surface of the monolayer tungsten diselenide, they find that the dark excitons couple to the surface fields generated and recombine to give off light quanta. Thus, the dark excitons are “brightened” with the help of the gold nanoparticles.

Unknown titled than the bright excitons. The dark excitons need an external influence to help them recombine. In their work, the IIT Madras researchers find exactly such an external influence.

Thus, the dark excitons are “brightened” with the help of the gold nanoparticles. “That plasmonic effect arises due to gold nanoparticles is a well known concept. But, its application to 2D systems is in nascent stage. So, I thought that if we drop-cast gold nanopart Summary
