Abstract

Lead halide perovskites (LHPs), have attracted considerable attention across various applications owing to their exceptional optoelectronic properties. However, the main challenge hindering the broad adoption of lead halide perovskites lies in their stability and toxicity. In this review, we summarize the outstanding properties of platinum (Pt) halide perovskites, with a particular focus on the stability and applications of Cs₂PtI₆ and its derivatives. Cs₂PtI₆ has shown promising efficiency for photovoltaic devices, as well as photoelectrochemical water splitting with stable behavior in acid or basic conditions. Cs₂PtI₆ also shows promise in gas sensing and thermoelectric devices. The emergence of 2D Pt (II) halide perovskites opens up new avenues for environmentally friendly materials for photonic and optoelectronic devices like room temperature phosphoresce and triplet-triplet annihilation (TTA) based up-conversion.

铂族和铂族过渡金属 0D 空位有序卤化物过磷酸盐：综述

卤化铅包晶石（LHPs）因其卓越的光电特性，在各种应用领域引起了广泛关注。然而，阻碍卤化铅包晶石广泛应用的主要挑战在于其稳定性和毒性。在这篇综述中，我们将总结卤化铂（Pt）包晶石的突出特性，并特别关注 Cs2PtI6 及其衍生物的稳定性和应用。Cs2PtI6 在光电设备以及光电化学水分离方面表现出良好的效率，在酸性或碱性条件下均表现稳定。Cs2PtI6 还有望用于气体传感和热电设备。二维卤化铂（II）包晶石的出现为用于光子和光电设备（如室温磷化和基于三重三重湮灭（TTA）的上转换）的环境友好型材料开辟了新的途径。
