QuantumWire

Recently, researchers from Pohang University of Science and Technology (POSTECH) have employed Nanoimprint Lithography (NIL) to fabricate metasurfaces embedded with quantum dots. The research team integrated quantum dots with titanium dioxide (TiO2) to create the metasurface. Unlike conventional methods, this approach embeds the quantum dots directly within the metasurface during its creation. Their experiments demonstrated that the more photons emitted from the quantum dots that were coupled to the resonant modes of the metasurface, the higher the luminescence efficiency. The team’s metasurface achieved up to 25 times greater luminescence efficiency compared to a simple coating of quantum dots.
