Material design for ceramic field emitter with high performance

在本研究中，我们试图完成材料设计，以获得高性能的陶瓷场发射器两年。（1）低能耗利用合成的ZnO：Al晶须场发射体，构建了场发射显示器。在20 × 30 mm^2的区域中，沉积红色和绿色磷光体并发射光。当能量为1 W时，获得的值为1400 cd/m^2。实现了10小时的操作。（2）稳定性在ZnO：Al晶须表面包覆MgO薄膜。这也有助于降低能量消耗并增加发射电流的稳定性。（3）长寿命MgO/ZnO：Al晶须场致发射体适合运行1000小时的性能。最后，晶须发射器已经工作了1000小时。

In this study, we try to complete material design in obtaining high performance of the ceramics field emitter for two years.(1)low energy consumptionUsing synthesized ZnO:Al whisker field emitter, Field emission display was constructed. In the area of 20 x30mm^2, red and green phosphors were deposited and emitted light. A value of 1400cd/m^2 was obtained for 1W energy. 10 hour operation was achieved.(2)stabilityMgO films were coated on the top of the ZnO:Al whiskers. This also contributes decrease in energy consumption and increase stability of emitted current.(3)long lifetimeMgO/ZnO:Al whisker field emitters were appropriate for operation of 1000h performance of the field emitter. Finally, the whisker emitter has worked for 1000h.
