沿着讨论了金属卤化物钙钛矿的不同合成方法和生长机理，以及它们的新特性和应用。纳米材料是指至少一个维度处于纳米级（即<100 nm）的那些材料，例如量子点、纳米线和纳米片。由于量子限制或强各向异性，这些类型的材料通常表现出与其体相对应物不同的光学和电学性质。从这个角度来看，我们将专注于一个特定的材料家族：金属卤化物钙钛矿，最近在光电子学和各种光子和光电应用中受到了极大的关注。不同的合成方法和生长机制将被讨论沿着与他们的新特性和应用。以钙钛矿量子点为例，量子限制效应和高外量子效率是这些新特性之一，并将讨论其在单光子发射器和LED等应用中的优异性能。了解这些纳米材料形式的钙钛矿形成背后的机制将有助于研究人员提出有效的策略来应对这一系列材料的新挑战，例如环境条件下的稳定性和毒性，以实现下一代光电子学和光电子学的应用。
The different synthesis approaches and growth mechanisms of metal halide perovskites will be discussed along with their novel characteristics and applications. Nanomaterials refer to those with at least one dimension being at the nanoscale (i.e. <100 nm) such as quantum dots, nanowires, and nanoplatelets. These types of materials normally exhibit optical and electrical properties distinct from their bulk counterparts due to quantum confinement or strong anisotropy. In this perspective, we will focus on a particular material family: metal halide perovskites, which have received tremendous interest recently in photovoltaics and diverse photonic and optoelectronic applications. The different synthesis approaches and growth mechanisms will be discussed along with their novel characteristics and applications. Taking perovskite quantum dots as an example, the quantum confinement effect and high external quantum efficiency are among these novel properties and their excellent performance in applications, such as single photon emitters and LEDs, will be discussed. Understanding the mechanism behind the formation of these nanomaterial forms of perovskite will help researchers to come up with effective strategies to combat the emerging challenges of this family of materials, such as stability under ambient conditions and toxicity, towards next generation applications in photovoltaics and optoelectronics.
