摘要

过氧化物具有诱人的光学和电学特性,使其成为具有低成本和直接制造工艺的高效发光材料的理想候选材料。它们的多功能性突出表现在能够在各种基底(包括硅、玻璃、蓝宝石和柔性基底)上沉积包晶体薄膜,从而有可能在硅上实现单片集成,用于光子集成电路和高速通信等应用。对包晶石发光二极管的广泛研究表明,在从深蓝到近红外的宽光谱范围内,其外部量子效率超过 20%,并具有手性。此外,在脉冲光激发、连续波操作以及功能二极管结构中,都实现了基于磷灰石的激光作用。然而,要在实际应用中实现电驱动包晶体激光二极管,需要注入高密度的电流。本综述全面概述了包晶体激光器和发光二极管的历史进程,以及对其发展至关重要的重要设计考虑因素。

Progress on Coherent Perovskites Emitters: From Light-Emitting Diodes under High Current Density Operation to Laser Diodes

Perovskites exhibit appealing optical and electrical properties, making them attractive candidates for efficient luminescent materials with low-cost and straightforward fabrication processes. Their versatility is highlighted by the ability to deposit perovskite thin films on various substrates, including silicon, glass, sapphire, and flexible substrates, enabling potential monolithic integration on silicon for applications such as photonic integrated circuits, high-speed communication. Extensive studies on perovskite light-emitting diodes have shown external quantum efficiencies exceeding 20% across a wide spectral range from deep blue to near-infrared, with chirality. Additionally, perovskite-based lasing action has been achieved under pulsed optical excitation and continuous-wave operation, as well as in functional diode structures. However, realizing electrically driven perovskite laser diodes for practical applications requires the injection of intense current densities. This review provides a comprehensive overview of the historical progress in perovskite lasers and light-emitting didoes, along with important design considerations essential for their development.
