标题： Nonequilibrium dynamics of localized and delocalized excitons in colloidal quantum dot solids

摘要： 自组装量子点（QD）固体是一类高度可调的材料，在固态电子和光电子器件中有广泛的应用。 在本文中，我们强调这些材料中微观无序的存在如何影响其宏观光电特性。 具体而言，我们使用理论模型框架来考虑能量无序QD固体中激子的动力学行为，包括局域和非局域激子区域。 在两种情况下，我们都强调能量无序促进非平衡弛豫动力学的趋势，并讨论这些非平衡效应的特征如何在时间依赖的光谱测量中表现出来。 此外，我们描述了材料内部激子微观动力学与材料特定参数测量之间的联系，例如发射线宽展宽和能量耗散率。 显示英文摘要

摘要： Self-assembled quantum dot (QD) solids are a highly tunable class of materials with a wide range of applications in solid-state electronics and optoelectronic devices. In this perspective, we highlight how the presence of microscopic disorder in these materials can influence their macroscopic optoelectronic properties. Specifically, we consider the dynamics of excitons in energetically disordered QD solids using a theoretical model framework for both localized and delocalized excitonic regimes. In both cases, we emphasize the tendency of energetic disorder to promote nonequilibrium relaxation dynamics and discuss how the signatures of these nonequilibrium effects manifest in time-dependent spectral measurements. Moreover, we describe the connection between the microscopic dynamics of excitons within the material and the measurement of material specific parameters, such as emission linewidth broadening and energetic dissipation rate.
