有机体系中激子极化激元研究进展

Research progress in exciton polaritons in organic systems

激子极化激元(EPs)是一种准粒子,是由光子与半导体材料激子强耦合形成。EPs具备光子速度快、相干性好和激子易调控等特点,并且由于其玻色子性质,可形成玻色-爱因斯坦凝聚(BEC)。相较于无机体系,有机体系更有利于实现室温下的凝聚,引起学术界的广泛兴趣。本文回顾了EPs的发展历程,深入介绍了基于有机体系EPs的机理、BEC、超流、涡旋形成和能量传递等的研究进展。

Exciton-polaritons(EPs)is a quasiparticle formed by the strong coupling between photons and excitons of the semiconductors.EPs possesses characteristics such as fast photon speed,good coherence,and easy exciton controllability.Due to its bosonic nature,EPs can form Bose-Einstein condensation(BEC).Compared to inorganic systems,organic systems are more conducive to achieving BEC at room temperature,sparking widespread interest in the academic community.This article reviews the development of EPs,and provides an in-depth exploration of the mechanisms,BEC,superfluidity,vortex formation,and energy transfer in organic systems-based research.
