Composition Tunable and Highly Luminescent Cesium Lead Halide Nanowires through Anion-exchange Reactions


Scientific Achievement

By combining a facial solution method with a post-synthetic approach, brightly emitting colloidal cesium lead halide (CsPbX3, X = Cl, Br, I) nanowires with uniform diameter and tunable composition have been successfully synthesized.

Significance and Impact

CsPbX3 nanowires show bright and tunable luminescence, and low defect density, which can serve as prospective materials for optoelectronic applications.
