All-liquid photonic microcavity stabilized by quantum dots.
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.
