Field emitters with excellent field emision properties based on suspended reduced graphene oxide (rGO) layer supported by tetrapod-like zinc oxide (T-ZnO) nanostructure were proposed. The T-ZnOs were transferred onto silver electrodes by screen-printing. Then, continuous and floating rGO films were deposited on the T-ZnO layer by spin-coating. The T-ZnO/rGO emitters exhibited field emission performances with higher emission current density and lower operation voltage when compared with the pure T-ZnO emitters. The results show that the T-ZnO/rGO emitters exhibited field emission properties with a turn-on field of 2.5 V/μm (current density as 10 μA/cm2) and a threshold field of 3.8 V/μm (current density as 1 mA/cm2).
