Investigation into the Photoluminescence Red Shift in Cesium Lead Bromide Nanocrystal Superlattices

Abstract

crystals on their surface, and up to 50 meV or more of the red shift coming from a photon propagation effect, specifically self-absorption. In addition, a self-assembly technique for growing micron-sized NC SLs on the surface of perfluorodecalin, an inert perfluorinated liquid and an antisolvent for NCs, is described.
