Abstract

We demonstrate two simple methods to fabricate QD-stabilized toluene microdroplets in water as whispering gallery mode microscale resonators in an all-liquid phase. The toluene microdroplets show size-dependently high Q-factors up to 5100 resulting from the stable QD-loaded microdroplets. The highly QD-stabilized toluene microdroplet resonators in the all-liquid phase would be promising for multiple all-liquid lasers.

摘要

我们展示了两种简单的方法，在全液相中制备了以量子点稳定的甲苯微滴作为 whispering gallery 模式微尺度谐振器。甲苯微滴表现出尺寸依赖性的高 Q 因子，最高可达 5100，这是由于稳定的量子点负载微滴的存在。这种高度稳定的全液相甲苯微滴谐振器有望应用于多种全液相激光器中。
