Abstract: Objective: The new energy-saving Nano-ZnO thin film lighting tube was innovated in this paper. Method: There are many ways to fabricate Nano-ZnO thin film, but it is difficult to produce the uniform thin film. Nano-ZnO thin film was fabricated by lower cost screen-printed, then, processed thin film with thermal sinter and anneal post-treatment. Result: Through thermal sinter and anneal post-treatment, the field emission was intentionally improved and made the stability and uniformity of emission became better. The fluorescence powder which at least one color was used at the anode electric film of lighting tube. Conclusion: After some measures, under the field emission, the uniformity of anode luminescent was stability. It indicated that the thermal sinter and anneal post-treatment intentionally improve field emission of Nano-ZnO thin film, it can be used in fabricate Nano-ZnO film cathode of field emission lighting tube. The result of the lighting tube research could be used in the fields of LED monitor and lighting equipment and so on, and it also could afford some theory evidence. The innovation is that the power consume of this new energy-saving Nano-ZnO thin film lighting tube was mW grade, it could save plenty of energy source.
