WebA 3D–3D flower-like bismuth bromide (BiOBr)/graphene hydrogel (BiOBr/GH) composite was synthesized via a two-step hydrothermal method. The scanning electron microscopy results confirmed that the three-dimensional (3D) flower-like BiOBr microspheres can be successfully loaded onto three-dimensional graphene oxide (GO) to form BiOBr/GH … WebFeb 17, 2024 · This study represents the heating-up synthesis of lead-free cesium bismuth bromide perovskite nanocrystals (NCs). CsBr and BiBr 3 precursors are used to synthesize uniform and phase-pure cesium bismuth bromide NCs, and the reaction is performed via an injection-free, heating-up method in the presence of a solvent mixture …
