文摘

The organic charge-transfer (CT) complexes nanostructures of CuTCNQF₄ and AgTCNQF₄ (copper/silver tetrafluorotetracyanoquinodimethane) were successfully fabricated by organic solid-phase reaction. The morphologies of CuTCNQF₄ and AgTCNQF₄ nanostructures can be easily tuned by controlling the reaction temperature. The electron field-emission properties on these nanostructures were investigated. The current density and turn-on field are 4.25 mA/cm² and 5.48 V/μm for the nanowires of CuTCNQF₄, and 1.82 mA/cm² and 5.21 V/μm for AgTCNQF₄, respectively. The results demonstrated that the nanostructures of complexes CuTCNQF₄ and AgTCNQF₄ were potential candidates for the field-emission cathode.
