Scientists Illuminate Dark Excitons in 2D Materials Using Plasmonic Tips

Researchers have made significant progress in controlling previously inaccessible dark excitons in 2D materials. The breakthrough involves using plasmonic tips to overcome fundamental limitations that have kept these quantum states dark and non-emissive.

Breakthrough in Dark Exciton Control

Scientists have developed a novel approach to activate and control dark excitons in tungsten diselenide (WSe₂) monolayers, according to recent research published in npj 2D Materials and Applications. The study reportedly demonstrates how plasmonic effects from metallic tips can brighten these typically non-radiative quantum states, overcoming fundamental limitations that have previously made them inaccessible for optical applications.
