Strategies on bandgap enlargement and proposed ideal structures for blue perovskite emitters

Caption

a, The structural formula of the metal-halide perovskite is ABX3, where A denotes monovalent cation, B denotes metal cations, and X generally denotes halide anions. n denotes the number of B-X octahedron layers between large intercalating cations. b, Proposed ideal perovskite blue NPLs in the dedicated device, and the controlled growth of perovskite NPLs from liquid intermediates on the pre-modified substrate in mild conditions. Note that the ligands are expected to locate at the interfaces between two charge-injection layers in the device.
