A new iodide layered double perovskite (CHNI)AgBiI (IPAB) has been developed based on a short-chain spacer cation, which is the first homologous compound in iodide double perovskites that adopt the Ruddlesden-Popper structure type. Importantly, IPAB is a promising environmentally friendly alternative to the recently rapidly progressing lead halide semiconductors owing to its narrow direct-bandgap of 1.87 eV and excellent stability.
一种基于短链间隔阳离子开发的新型碘化物层状双钙钛矿(CHNI)AgBiI(IPAB)，它是采用Ruddlesden-Popper结构类型的碘化物双钙钛矿中的首个同系化合物。重要的是，由于其1.87 eV的窄直接带隙和出色的稳定性，IPAB是最近快速发展的卤化铅半导体的一种有前景的环保替代品。
