Abstract

The direct generation of efficient, tunable, and switchable circularly polarized laser emission (CPLE) would have far-reaching implications in photonics and material sciences. In this paper, we describe the first chiral simple organic molecules (SOMs) capable of simultaneously sustaining significant chemical robustness, high fluorescence quantum yields, and circularly polarized luminescence (CPL) ellipticity levels (||) comparable to those of similar CPL-SOMs. All these parameters altogether enable efficient laser emission and CPLE with ellipticity levels 2 orders of magnitude stronger than the intrinsic CPL ones.

摘要

直接产生高效、可调谐且可切换的圆偏振激光发射(CPLE)将在光子学和材料科学领域产生深远影响。在本文中,我们描述了首例手性简单有机分子(SOM),其能够同时保持显著的化学稳定性、高荧光量子产率以及与类似的圆偏振发光(CPL)-SOM相当的圆偏振发光(CPL)椭圆率水平(||)。所有这些参数共同实现了高效激光发射和CPLE,其椭圆率水平比固有CPL的椭圆率水平强2个数量级。
