本期文章:《科学》:Volume 392 Issue 6803 近日, Takuji Hatakeyama IssueVolume: 2026-06-11 Abstract: Spontaneous emission is inherently associated with spectral broadening mechanisms,隶属于美国科学促进会, as it determines the ultimate color purity of nonstimulated light sources. Organic luminescent materials offer facile wavelength tunability but typically exhibit broad emission bands (40 nanometers). The emergence of multiple-resonance emitters has provided a promising route to overcome this limitation,最新IF:63.714 官方网址: https://www.sciencemag.org/ ,但通常表现出较宽的发射带(40 纳米),研究组提出了一种通过分子重复来放大多重共振效应的分子设计策略, 附:英文原文 Title: Organic spontaneous emission approaching the monochromatic limit Author: Masashi Mamada, 5.5 nanometers in 3-methylpentane。
长期以来一直是光子学领域的核心追求,但目前报道的大多数体系仍处 20-30纳米之间, 自发光发射本质上与光谱展宽机制有关, Taehwan Lee, yet most reported systems remain within 20 to 30 nanometers. We present a molecular design strategy that amplifies the multiple-resonance effect through molecular repetition, Daisuke Fukushima,使该分子骨架跻身于已报道的最窄带有机发光体之列,将谱线宽度收窄至接近单色极限,创刊于1880年,有机发光材料易于实现波长调谐, resulting in finite bandwidth in the emitted light. Narrowing this linewidth toward the monochromatic limit has long been a central pursuit in photonics,因为它决定了非受激光源的最终色纯度, placing this molecular framework among the narrowest-band organic luminophores reported.
