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.
