Ultrathin Colloidal Cesium Lead Halide Perovskite Nanowires

Scientific Achievement

Highly uniform single crystal ultrathin CsPbBr3 nanowires with diameter of 2.2 nm and length up to several microns were successfully synthesized and purified using a catalyst-free colloidal method.

Significance and Impact

These bright ultrathin nanowires can serve as a model system to study strong quantum confinement effects in a one-dimensional halide perovskite system.
