Abstract

Random lasing occurs as a result of coherent optical feedback from random scattering centers. Plasmonic nanostructures, such as silver or gold nanoparticles, efficiently scatter light due to the formation of hot spots and optical confinement at the nanoscale. In this work, using silver nanocubes as highly efficient light scattering centers, a broadband plasmon assisted lasing action of halide perovskite materials is demonstrated. By embedding silver nanocubes in CH₃NH₃PbBr₃ and CH₃NH₃PbI₃ solutions, narrow bandwidth lasing modes with a full width at half-maximum of approximately 1 nm are supported. It is observed that the lasing thresholds of perovskites differ for glass and gold substrates (18.05 vs. 16.50 W/cm²) and for different nanocube concentrations. Results of time-resolved measurements indicate a significant shortening in the decay time of the emission above the lasing threshold, implying a stimulated emission process. The results of this work thus provide a pathway to generate coherent light sources from widely studied perovskite materials.

银纳米立方辅助钙钛矿材料的随机激光

随机激光是随机散射中心的相干光反馈的结果。等离子体纳米结构，如银或金纳米粒子，由于在纳米尺度上形成热点和光学限制而有效地散射光。在这项工作中，利用银纳米立方体作为高效的光散射中心，证明了卤化物钙钛矿材料的宽带等离子体辅助激光作用。通过在CH3NH3PbBr3和CH3NH3PbI3溶液中嵌入银纳米立方体，可以支持全宽约为1 nm的窄带宽激光模式。观察到，钙钛矿的激光阈值在玻璃和金衬底（18.05 vs. 16.50 W/cm2）和不同纳米立方浓度下是不同的。时间分辨测量结果表明，在激光阈值以上，发射的衰减时间显著缩短，这意味着一个受激发射过程。因此，这项工作的结果为从广泛研究的钙钛矿材料中产生相干光源提供了一条途径。

期刊介绍： The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
