研究了流体自组装球相液晶的随机激光，该液晶由三维扭曲球结构组成，球结构之间存在向错。由于随机分布的球相片晶的多重散射产生的干涉，球相液晶随机激光的阈值能量是手性液晶的32%。这种由自组装软有机材料组成的随机激光器可用于全息显示器、即时生物医学分析和光学安全涂层。(C)2015年AIP Publishing LLC。
We investigated random lasing from a fluid self-assembly sphere-phase liquid crystal, which was composed of three-dimensional twist sphere structures with disclinations among them. The threshold energy of the random lasing from sphere-phase liquid crystal was 32% of that from the chiral nematic phase because of the interference associated with multiple scattering by randomly distributed sphere-phase platelets. Such random lasers composed of self-assembly soft organic materials may be useful for holographic displays, point-of-care biomedical analysis, and optical security coatings.
