Red-emissive carbon dots (CDs) with high PLQY (65.5 %) were obtained from aliphatic precursors by combining graphitic nitrogen doping and surface modification. A planar microcavity with only one resonant mode, which fitted with the CDs’ amplified spontaneous emission (ASE) peak, was constructed and resulted in a solid-state laser with a single longitudinal mode, a linewidth of 0.14 nm and a signal-to-noise ratio of 14.8 dB.

来自碳点的具有单纵模的固态红光激光器

通过结合石墨氮掺杂和表面改性，从脂肪族前驱体中获得了具有高 PLQY (65.5%) 的红色发射碳点 (CD)。构建了一个只有一个谐振模式的平面微腔，它与 CD 的放大自发发射 (ASE) 峰值相吻合，并产生了一个具有单纵模、线宽为 0.14 nm 和信号到-的固态激光器。噪声比为 14.8 dB。
