Field Emission Properties of Tetrapod-Like ZnO Coated with Nickel by Electroless Deposition

Translated Abstract

Tetrapod-like　ZnO　(　T-ZnO)　powders　synthesized　via　chemical　vapor　deposition　(　CVD)　were　transferred　to　ITO　substrates　coated　with　silver　paste,　followed　by　nickel　coating　through　electroless　plat-ing,　to　fabricate　the　novel　T-ZnO/Ni　cathodes.　The　morphologies　of　T-ZnO　powder,　T-ZnO　cathodes　and　T-ZnO/Ni　cathodes　were　investigated　by　scanning　electron　microscopy　(　SEM)　and　transmission　electron　microscopy　(　TEM　)　.　The　composition　and　structure　of　T-ZnO/Ni　cathodes　were　characterized　by　X-ray　energy　dispersive　spectroscopy　(　EDS)　and　X-ray　diffraction　(　XRD)　,　respectively.　The　results　indicate　that　disordered　microcrystal　nickel　was　deposited　on　the　surface　of　T-ZnO/Ni　cathode　after　electroless　nickel-plating　on　T-ZnO　cathode.　The　turn-on　field　of　T-ZnO/Ni　cathode　was　reduced　to　1.　60　V/μm　and　the　field　enhancement　factor　was　enhanced　to　7　190　.
