Vortex fluidic enabling and significantly boosting light intensity of graphene oxide with aggregation induced emission luminogen

Abstract

Graphene oxide (GO) has been well recognized as an effective fluorescence (FL) quenching material, reducing the brightness of fluorophores. In contrast to this, we have discovered a novel and cost-effective approach to produce GO/aggregation-induced emission (AIE) demonstrating high fluorescent performance. Under a dynamic thin-film microfluidic platform, known as a vortex fluidic device (VFD), GO/AIE was about 4 times or 14 times brighter than that prepared by batch production or the AIE alone. The fluorescent property of the GO/AIE depends on the concentration of GO, the rotation speed of the VFD tube, and the water fraction.
