In recent years,great progress has been achieved for organic-inorganic halide perovskites due to their excellent optoelectronic properties and stability for photovoltaics,light emitting diodes,and high-energy radiation detection [1-5].One-dimensional (1D)perovskites,as an important derivative of three-dimensional (3D)perovskites,exhibit low exciton dissociation efficiency,which can produce strong quantum confinement and form self-trapping excited state [6].In addition,the hydrophobic properties and the inhibition of ion migration from large organic cations improve the moisture and thermal stability for optoelectronic devices.Therefore,functional materials for various optoelectronic applica-tions can be sought out in 1D perovskites by adjusting composition appropriately and flexibly [7].
