论文摘要
有机半导体是环境极化的有前途的平台。由于有机物的超短发行寿命,目前阻碍了几种应用,例如北极星路由器和多体凝结物质现象。在这里,我们采用了一种使用4纳秒长的非谐波激发脉冲来研究polariton las的单一色散成像技术,以$λ/2 $平面有机微腔内充满了bodipipy-br染料分子。 At a power threshold density of $1.5 MW/cm^{2}$, we observe the transition to a quasi-steady state, 1.2 ns long-lived, single-mode polariton lasing and the concomitant superlinear increase of photoluminescence, spectral line-narrowing, and energy blueshift
Organic semiconductors are a promising platform for ambient polaritonics. Several applications, such as polariton routers, and many-body condensed matter phenomena are currently hindered due to the ultra-short polariton lifetimes in organics. Here, we employ a single-shot dispersion imaging technique, using 4 nanosecond long non-resonant excitation pulses, to study polariton lasing in a $λ/2$ planar organic microcavity filled with BODIPY-Br dye molecules. At a power threshold density of $1.5 MW/cm^{2}$, we observe the transition to a quasi-steady state, 1.2 ns long-lived, single-mode polariton lasing and the concomitant superlinear increase of photoluminescence, spectral line-narrowing, and energy blueshift
