Photonics in Flatland: Band Structure Engineering of 2D Excitons in Fluorescent Colloidal Nanomaterials Ghent University
In PHOCONA we aim to develop a new class of highly fluorescent 2D and quasi-2D colloidal nanomaterials for solution-processed coherent light sources and ultrafast single-photon emitters. The 2D excitons are created in suspended semiconductor nanoplates with a thickness below 5 nm, and transition-metal dichalcogenide monolayers. Prepared by colloidal chemistry and liquid-phase exfoliation, respectively, they take advantage of both quantum ...
