In–In₂O₃ composite nanopagodas demonstrate excellent field emission properties with an enhanced kinetics factor (saturation ratio). The turn-on fields and β of the In–In₂O₃ nanopagodas were 2.0 V μm⁻¹ and 3590. The indium of the In–In₂O₃ nanopagodas accumulates electrons and forms electron tunnels, which enhances the field emission properties.
