摘要

卤化铅过氧化物（LHP）纳米晶体（NCs）因其优异的性能和在光电子学和光伏学领域广泛应用的巨大潜力，正在蓬勃发展。然而，尽管该领域发展势头迅猛，但由于内在相变以及湿度、温度和紫外线（UV）等外部因素导致的降解，过氧化物器件尚未做好商业化的准备。为了实现长期稳定性，我们分析了不稳定性的起源，并介绍了不同的策略，如表面改性、封装和掺杂，以实现长期可行性。我们还评估了如何利用这些稳定策略获得具有长期稳定性的光电器件。本微型综述还概述了每种策略的未来发展方向，以生产出高效、超稳定的 LHP NCs，实现可持续应用。

Strategies To Achieve Long-Term Stability in Lead Halide Perovskite Nanocrystals and Its Optoelectronic Applications

The lead halide perovskite (LHP) nanocrystals (NCs) research area is flourishing due to their exceptional properties and great potential for a wide range of applications in optoelectronics and photovoltaics. Yet, despite the momentum in the field, perovskite devices are not yet ready for commercialization due to degradation caused by intrinsic phase transitions and external factors such as moisture, temperature, and ultraviolet (UV) light. To attain long-term stability, we analyze the origin of instabilities and describe different strategies such as surface modification, encapsulation, and doping for long-term viability. We also assess how these stabilizing strategies have been utilized to obtain optoelectronic devices with long-term stability. This Mini-Review also outlines the future direction of each strategy for producing highly efficient and ultrastable LHP NCs for sustainable applications.
