Abstract

Lead-free halide double perovskites (DPs) have been regarded as a class of environmentally friendly and promising optoelectronic materials. Herein, we report the synthesis, luminescence properties, and optoelectronic applications of lanthanide (Ln = Yb3+/Er3+)/M (M = Bi3+/Sb3+/Mn2+) codoped Cs2NaInCl6 single crystals (SCs). The Yb/Er codoped Cs2NaInCl6 SCs show upconversion and downshifting visible/short-wave infrared (SWIR) photoluminescence emission. After further introduction of Sb3+/Mn2+ ions into the host, bright blue and red emissions are observed with the PLQYs of 96.28% and 21.58%, respectively. With the incorporation of Bi3+ ions, the upconversion and visible/SWIR luminescence intensities of Yb/Er/Bi codoped Cs2NaInCl6 SCs are significantly enhanced. The incorporation of Bi3+ dopant in the DP host can construct a more efficient energy transfer process, resulting in excellent luminescence efficiency. The multi-ion codoped DP system exhibits great potential for optoelectronic applications in the fields of anticounterfeiting, photodetector, and x-ray imaging. This work will help guide the design and development of environmentally friendly multi-functional materials.

采用多离子共掺杂策略实现环保卤化物双钙钛矿的多用途光电应用

无铅卤化物双钙钛矿（DPs）被认为是一类环保且有发展前途的光电材料。本文报道了镧系元素(Ln = Yb3+/Er3+)/M （M = Bi3+/Sb3+/Mn2+）共掺杂Cs2NaInCl6单晶（SCs）的合成、发光特性及光电应用。Yb/Er共掺杂的Cs2NaInCl6 SCs表现出上转换和下移的可见/短波红外（SWIR）光致发光发射。进一步引入Sb3+/Mn2+离子后，可以观察到明亮的蓝色和红色发射，plqy分别为96.28%和21.58%。随着Bi3+离子的掺入，Yb/Er/Bi共掺杂Cs2NaInCl6 SCs的上转换和可见光/SWIR发光强度显著增强。Bi3+掺杂剂掺入DP主体可以构建更高效的能量传递过程，从而获得优异的发光效率。多离子共掺杂DP体系在防伪、光电探测、x射线成像等领域具有广阔的光电应用前景。这项工作将有助于指导环保多功能材料的设计和开发。
