摘要
有机-无机杂化钙钛矿具有载流子扩散长度长、发光效率高等特点,是一种性能优良的半导体材料,也是一种极具潜力的激光增益介质,受到了光伏、激光等多个领域的广泛关注。概述了利用有机-无机杂化钙钛矿作为增益介质研发的薄膜型多晶钙钛矿激光器、单晶钙钛矿激光器以及微盘钙钛矿激光器的研究进展。介绍了具有优异的电学性能和光学性能的有机-无机杂化钙钛矿制备方法,分析了影响有机-无机杂化钙钛矿激光器性能的主要因素。结果表明,相对于其他类型的激光器,单晶钙钛矿纳米线结构具有更低的激光阈值、更窄的光谱宽度,是实现纳米激光的最佳选择之一。此外,针对有机-无机杂化钙钛矿激光器目前存在的钙钛矿材料的降解、实现电泵浦激光所需电流密度高等问题,对今后钙钛矿激光器的研究重点和发展趋势进行展望。
        Organic-inorganic hybridized perovskite,which is an excellent semiconductor material and a promising laser gain medium due to its good properties of long carrier diffusion length,high luminous efficiency,etc.,has attracted widespread attention in many fields such as photovoltaics,laser and so on. Research progresses of lasers using organic-inorganic hybridized perovskite as gain medium are summarized,including polycrystalline thin film perovskite lasers,single crystalline perovskite lasers and micro-disk perovskite lasers. The preparation methods of organic-inorganic hybridized perovskites with excellent electrical and optical properties are reviewed,and the main factors affecting the performance of organic-inorganic hybridized perovskites lasers are analyzed. The results show that single crystalline nanowire structures,which have lower laser threshold and narrower spectral width than other types of perovskite lasers,are one of the best choices for nanolasers. In addition,in view of the problems in organic-inorganic hybridized perovskite lasers such as material degradation and higher current densities required for electrically driven laser,the research focus and development trends of perovskite lasers in the future are forecasted.
