原文开头
Masashi Mamada1, Kota Kataoka1, Junki Ochi1, Taehwan Lee1, Ryuji Matsumoto2, Mayu Yoshioka3, Daisuke Fukushima4, Takuji Hatakeyama1* Spontaneous emission is inherently associated with spectral broadening mechanisms, resulting in finite bandwidth in the emitted light. narrowing this linewidth toward the monochromatic limit has long been a central pursuit in photonics, 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, yet most reported systems remain within 20 to 30 nanometers. …
