Abstract：

A　facile　solution　route　of　self-assembled　zinc　oxide　(ZnO)　nanoparticles　(NPs)　on　the　surface　of　cupric　oxide　(CuO)　nanowires　(NWs)　was　presented,　and　field　emission　arrays　with　ZnO　NPs-CuO　NWs　hybrid　emitters　were　fabricated.　The　NW　based　conjugation　by　coating　ZnO　NPs　on　CuO　NWs　was　confirmed　by　transmission　electron　microscopy　(TEM)　image.　The　turn　on　electric　fields　of　the　ZnO　NPs-CuO　NWs　hybrid　emitters　decreased　to　2·37　V　μm-1　compared　with　4·95　V　μm-1　of　pure　CuO　NWs,　and　the　field　enhancement　factor　was　significantly　enhanced　from　~869　(pure　CuO　NWs)　to　~1678　(ZnO　NPs-CuO　NWs).　The　ZnO-CuO　NWs　hybrid　emitters　also　have　higher　emitting　uniformity,　which　indicated　the　efficient　field　emission　properties　for　the　hybrid　emitters.　©　2015　W.　S.　Maney　&　Son　Ltd.
