Abstract:A mixed passivation strategy is deployed to produce monodisperse and pure CsPbBr3 nanocrystals under ambient condition via post treatment using ZnBr2 in mixed organic solvents. This room temperature synthesis route provides precise size and shape control, and colloidal nanocubes or nanospheres can be obtained depending on the choice of organic solvents. Any secondary phases’ nucleation was inhibited. The ZnBr2 can reduce the Br− vacancies at the surface termination layers, thus enhancing their properties. This… Show more
“…In particular, the quantum dots show high selectivity and rapid detection of Fe 3+ , CrO 4 2− , and Cr 2 O7 2− ions in an aqueous solution with good anti-interference ability. Foo et al 48 achieve the production of monodisperse and pure CsPbBr 3 nanocrystals with precise size and shape control under ambient conditions using a mixed passivation strategy. This work offers a cheap and viable approach for the preparation of perovskite nanocrystals in optical and electrical devices.…”
