Herein, we report the optical properties of ZnO NP-rGO nanocomposites and fabricated light-emitting diodes (LEDs) that exhibited green electroluminescence. The external quantum efficiency of the LEDs was 0.22%, which is the highest value ever reported for LEDs based on rGO. The weak optical behavior of rGO was improved by adding ZnO NPs, and green emission was observed in these functionalized rGO-based nanocomposites. This study provides an effective method for expanding the optoelectronic applications of rGO.
