| Abstract |
Perovskites (CsPbX3, X=Cl, Br, and I) have attracted enormous interest as excellent light absorber material in photovoltaics with the power conversion efficiency exceeding 20% owing to their excellent optical and optoelectronic properties. However, they exhibit limited stability due to thermal degradation and hydrolysis by atmospheric water. In this study, we report the synthesis of Cs4PbX6 perovskite nanowires, where X = Cl, Br, and I, using vapor transport method. The perovskite nanowires exhibit a uniform growth direction, smooth surfaces, straight end facets, and homogeneous composition distributions. The nanowires were prepared using three different compositions of halides, which showed that the band gap was successfully tuned over a wide range. We found that the Cs4PbX6 nanowires exhibit the higher stability than the CsPbX3 nanowires, which can provide advantageous for fabricating the nanowire lasers that exhibit good crystal qualities and strong light-matter interactions.
