Abstract
We demonstrated a way to achieve tunable fluorescence from reduced graphene oxide (rGO) by selecting appropriate solvents. This work begins a new area of research that seeks to improve the fluorescence properties of rGO, offering novel strategies for realizing printed flexible opto-electronics with tunable device performance. We investigated the effect of solvents and report that solvents play a vital role in the optical properties of rGO. The dispersion of rGO was analyzed by UV–Visible spectroscopy, FTIR spectroscopy, and fluorescence spectroscopy, demonstrating that rGO dissolved in polar solvents exhibits enhanced fluorescence covering the entire visible range as opposed to non-polar solvents. The synthesis strategy may possibly facilitate the manipulation and processing of rGO toward vital printed flexible optoelectronics applications, which could be tuned by selecting a suitable solvent.
