Abstract：

Bi2O3　nanowires　were　synthesized　from　NaOH　and　Bi(NO3)3　·　5H2O　with　surfactants　oleic　acid,　heptane　and　acetone　added　at　room-temperature.　The　nanowires　have　a　diameter　of　about　50nm　and　a　length　in　the　range　of　several　to　tens　of　micrometers.　X-ray　diffraction　(XRD)　analysis　and　scanning　electron　microscopy　(SEM)　were　employed　to　characterize　the　structure　and　morphology　of　these　structures.　The　cathode　array　was　prepared　by　screen-printed.　The　field　emission　of　the　sample　started　at　a　turn-on　field　of　2.6　V/μm　at　a　current　density　of　0.1　μA/cm2.　This　type　of　Bi2O3　nanowires　can　be　applied　as　field　emitters　in　displays　as　well　as　vacuum　electric　devices.
