Abstract

Novel lead-free non-perovskite blue-emitting cesium bromine (CsBr) QDs have been prepared using a ligand-assisted re-precipitation method. A high photoluminescence quantum yield of over 92.0% makes the CsBr QDs an efficient color-conversion candidate for fabricating white-light-emitting diodes.
