论文摘要
铅卤化物钙钛矿是一种非凡的材料类，在过去的十年中出现，适合在广泛的设备中应用，例如太阳能电池，发光二极管，激光器，晶体管和存储器等。尽管它们通常是在低温下沉积的溶液处理的半导体，但钙钛矿表现出人们只能在高温下生长的高度纯无机晶体所期望的特性。这种独特的现象导致了迈向创纪录的设备性能的快节奏。不幸的是，这些材料的非凡性质背后的基础科学仍然不太了解。这篇综述评估了金属卤化物钙钛矿材料的光致发光（PL）特性的当前理解，并突出了需要进一步研究的关键领域。此外，要强调为了提高可比性，可靠性和可重复性的标准化PL表征方法的需求。
Lead halide perovskites are a remarkable class of materials that have emerged over the past decade as being suitable for application in a broad range of devices, such as solar cells, light-emitting diodes, lasers, transistors, and memory devices, among others. While they are often solution-processed semiconductors deposited at low temperatures, perovskites exhibit properties one would only expect from highly pure inorganic crystals that are grown at high temperatures. This unique phenomenon has resulted in fast-paced progress toward record device performance; unfortunately, the basic science behind the remarkable nature of these materials is still not well understood. This review assesses the current understanding of the photoluminescence (PL) properties of metal halide perovskite materials and highlights key areas that require further research. Furthermore, the need to standardize the methods for characterization of PL in order to improve comparability, reliability and reproducibility of results is emphasized.
