Lead-halide perovskite nanoparticles（LHP NPs） are highly promising materials for next-generation displays and solid-state lighting due to their exceptional optical properties. However, their inherent instability presents a significant challenge. Recent advances have demonstrated that optoelectronic devices based on monolayer nanoparticle films exhibit both high luminescence efficiency and long-term *** research demonstrates that mobility limitations and anisotropic alignments in CsPbBr3nanocube monolayer films are key to their stabilization, hindering spontaneous growth through face-to-face fusion and resulting in the formation of connecting necks in a diagonal direction. Introducing laser irradiation confirmed this by significantly accelerating nanocubes growth, increasing mobility, and enhancing local structural ordering, leading to larger and more regularly shaped nanosheets. Fourier transform infrared spectroscopy and energy dispersive spectroscopy line-scan analyses indicated that laser irradiation did not disrupt the ligand structure. Transmission electron microscopy and correlative cathodoluminescence electron microscopy revealed the effects of post-growth and heterogeneous structures, including enhanced luminescence and inhomogeneous intensity in the nanosheets. These findings deepen the understanding of the post-growth mechanism of monolayer nanoparticles and the structure-emission correlation and highlight the unique role of laser irradiation in directing the formation of well-defined and regular nanostructures.

五四运动爆发后,日本主流舆论将其定性为“排日运动”,多指责中国青年学生排斥日本,认为英美势力与中国亲英美派政客煽动青年学生促成了“暴动”。部分日本在华媒体人和以吉野作造为代表的日本新知识分子以及大阪报刊《大正日日新闻》却肯定了五四运动体现出的进步思想,呼吁日本民众理性看待中国的民众运动。其中,《大正日日新闻》1920年新年号连载“中国名士之对日意见”,这些意见集中介绍了五四运动、新思想运动的真义,体现了五四运动后日本知识界对中国新思想的关注,同时也呈现出日本对华观的多面性与复杂性。
