Abstract

Stimuli-responsive photoluminescent halide double perovskites present environmentally benign alternatives to lead-based systems for sensing and information encryption. Here, we report acetone-induced rapid transformation of a yellow-emissive (λ_em = 585 nm), one-dimensional (CH₃NH₃)₂NaInBr₆:Sb double perovskite to an orange-emissive (λ_em = 660 nm), zero-dimensional (CH₃NH₃)₄InBr₇:Sb compound. This structural and optical switching occurs within seconds and is reversible over multiple cycles. This study presents a rare example of solvatochromism in a hybrid In(III)-based halide double perovskite, significantly expanding the scope of this important class of materials for optical switching applications.

无铅sb掺杂（CH3NH3）2NaInBr6双钙钛矿结构尺寸快速可逆的光致发光开关

刺激响应光致发光卤化物双钙钛矿为传感和信息加密提供了铅基系统的环保替代品。在这里，我们报道了丙酮诱导的黄色发射（λem = 585 nm）、一维（CH3NH3）2NaInBr6:Sb双钙钛矿向橙色发射（λem = 660 nm）、零维（CH3NH3）4InBr7:Sb化合物的快速转化。这种结构和光交换在几秒钟内发生，并且在多个周期内可逆。这项研究提出了一个罕见的in （III）基卤化物双钙钛矿的溶剂化变色的例子，极大地扩展了这类重要材料在光开关应用中的范围。
