Cs3Cu2I5 and CsCu2I3 have been demonstrated to emit broad spectrum light with high photoluminescence quantum efficiency (PLQY) due to their low-dimensional electronic structure and soft lattice with a strong electron–phonon coupling. Owing to their advantages of non-toxicity, simple synthesis method, high air stability and thermal stability, they have become one of the most promising semiconductors for next-generation optoelectronic devices. There are two explanations for the mechanism of their broad-spectrum luminescence, that is, self-trapped exciton (STE) luminescence and excited-state structure reorganization. We sort out the halogen composition-related PL, temperature-dependent PL and theoretical calculations of Cs3Cu2I5 and CsCu2I3 in recent years to review the mechanism of this broad spectrum luminescence from the perspectives of electronic dimensions and lattice distortion. In addition, current application status and future prospects of Cs3Cu2I5 and CsCu2I3 in optoelectronic fields are also presented in this review.

Cs3Cu2I5 和 CsCu2I3 中的光物理

Cs 3 Cu 2 I 5和CsCu 2 I 3由于其低维电子结构和具有强电子 - 声子耦合的软晶格,已被证明可以发射具有高光致发光量子效率(PLQY)的广谱光。由于其无毒、合成方法简单、空气稳定性和热稳定性高等优点,它们已成为下一代光电器件最有前途的半导体之一。它们的广谱发光机制有两种解释,即自陷激子(STE)发光和激发态结构重组。我们梳理了Cs 3 Cu 2 I 5和CsCu 2 I 3的卤素成分相关PL、温度相关PL和理论计算近年来从电子维度和晶格畸变的角度回顾了这种广谱发光的机制。此外,本文还介绍了Cs 3 Cu 2 I 5和CsCu 2 I 3在光电领域的应用现状和未来前景。
