Roles of ligand and solvent for CsPbBr3 nanoplatelets

Crystal structures and photoluminescence characteristics of cesium lead bromide perovskite nanoplatelets depending on the antisolvent and ligand used in their syntheses

“…All-inorganic perovskites can be synthesized using various methods, such as hot injection [ 14 ], ligand-assisted reprecipitation (LARP) [ 15 ], ultrasonication [ 16 ], and indirect (two-step) synthesis [ 17 ]. In the LARP method, CsBr and PbBr 2 are dissolved in a solvent to form a CsPbBr 3 precursor solution, in which ligands are added to control the formation of perovskite NCs [ [18] , [19] , [20] ]. An antisolvent was dripped into the precursor solution to induce fast (or intermediate) precipitation of perovskite NCs [ 21 ].…”

CsPbX3 (X = Cl, Br, and I) Nanocrystals in Substrates toward Stable Photoluminescence: Nanoarchitectonics, Properties, and Applications

“…and abundant structures (ranging from zero dimensional (0D) to three-dimensional (3D)) as well as the outstanding photoluminescence (PL) properties of the perovskite nanomaterials, these materials have been widely studied for a variety of applications. And the PL properties of these nanomaterials are often dependent on their compositions, structures, dimensions, sizes and morphologies. − …”
